AP Physics C. AP Physics 1 and AP Physics 2 are algebra based and AP Physics C, calculus based.
AP Physics 1
The exam is approximately three hours long, with multiple choice and free response questions, with duration
of 1 hour and 30 minutes each, carrying equal credit. The free response section contains 6–7 questions. Typically,
one question is laboratory-based.
An algebra-based, introductory college-level physics course. Main topics include:
Kinematics: Describes motion using position, displacement, and acceleration, but not the causes of motion (i.e., forces).
Symbols:
$\vec{v}$ = velocity (vector),
$\vec{x}$ = position (vector in 1D or higher dimensions),
$\Delta \vec{x}$ = displacement (vector change in position),
$t$ = time (scalar),
$\vec{a}$ = acceleration (vector).
These equations predict future motion (position and velocity at any time t) when the initial conditions are known. Initial conditions refer to the state of the object at the start of
observation—specifically, its initial position ($\vec{x}_i$) and initial velocity ($\vec{v}_i$)—along with the constant acceleration ($\vec{a}$) acting on it.
Practice Kinematics Problem Types:
These problem types involve using kinematics equations where the acceleration is constant and zero in the case of constant-speed motion.
Motion in a straight line; Free-fall motion; Motion along an incline; 2D motion (e.g., projectiles).
Kinematics diagram: Displacement (Δx), velocity (v), and acceleration (a) are vector quantities in
the direction as indicated by the respective arrow.
Dynamics: Studies the forces that cause motion, using Newton’s Laws.
Symbols: $\vec{F}_{\text{net}}$ = net force, $\vec{f}_{\text{fric}}$ = force of friction, $m$ = mass, $\vec{a}$ = acceleration, $\mu$ = coefficient of friction, $\vec{N}$ = normal force.
Practice Dynamics Problem Types:
These problem types involve using Newton's Laws to analyze forces and motion.
Motion on a horizontal surface with and without friction; Inclined plane problems with and without friction; Pulley systems involving tension forces for objects in gravity and on horizontal or inclined planes; Circular motion (e.g., centripetal force).
Dynamics using Newton's Second Law: Forces on a block being pushed right.
mg = weight (down), N = normal force (up), F = applied push (right), f = kinetic friction (left).
Circular Motion and Gravitation: Covers uniform circular motion and Newton’s law of gravitation.
Used in orbital motion and centripetal force problems.
Practice Circular Motion and Gravitation Problem Types:
These problem types involve motion where a net force acts toward the center.
Uniform circular motion at constant speed; circular motion due to tension in a string; circular motion due to friction on a surface such as a road during vehicle turning; satellite motion around Earth.
Uniform circular motion: A mass m moves in a circle with constant speed.
The net force F (centripetal) points toward the center and causes centripetal or radial acceleration.
Energy: Focuses on kinetic and potential energy and conservation.
Equations: $KE = \tfrac{1}{2} m v^2$, $PE_g = m g h$, $W = F d \cos\theta$, $\Delta E_{\text{total}} = 0$ (isolated)
Symbols: $KE$ = kinetic energy (scalar), $PE_g$ = gravitational potential energy (scalar), $W$ = work (scalar), $F$ = magnitude of force (scalar), $d$ = magnitude of displacement (scalar), $\theta$ = angle between force and displacement vectors.

These problem types involve changes in kinetic or potential energy, work done by forces, or conservation of mechanical energy in isolated systems.
A block sliding down a frictionless incline; a block sliding down an incline with friction; a mass-spring system oscillating on a horizontal surface; a simple pendulum swinging between its lowest and highest points;
an object lifted vertically at constant speed; a vertical spring with a hanging mass.
Work and energy on an incline:
Weight mg acts downward. Weight component along frictionless ramp is mgsinθ, and d is displacement along inclined plane, so the work done is W = (mgsinθ)d = mgh.
Momentum: Covers conservation during collisions and impulse.
Equations: $\vec{p} = m \vec{v}$, $\vec{J} = \vec{F} \Delta t = \Delta \vec{p}$, $\displaystyle \sum \vec{p}_{\text{before}} = \sum \vec{p}_{\text{after}}$
These problem types involve collisions, explosions, or impulse situations in which the net external force on the system is negligible, so momentum is conserved.
Two carts colliding and sticking together on a track (perfectly inelastic collision); two carts colliding and bouncing apart (elastic or partially elastic collision); a person jumping off a stationary cart; two skaters pushing off each other on ice; a ball bouncing off a wall or the floor.
Conservation of momentum in a collision:
Two carts approach each other with momenta p1 and p2.
In the absence of external forces, the total momentum before collision equals the total after.
Simple Harmonic Motion: Describes oscillations like springs and pendulums.
Symbols: $k$ = spring constant (scalar), $L$ = pendulum length (scalar), $g$ = gravitational field strength (scalar).

The restoring force F = −kx acts opposite to displacement x from equilibrium,
producing oscillatory motion with period T = 2π√(m/k).

These problem types involve objects rotating about a fixed axis where net torque causes angular acceleration.
A horizontal beam balanced on a pivot with masses hanging from it (static equilibrium); a disk or pulley with a string wrapped around it and a hanging mass; a rod rotating on a hinge when released from horizontal; a wheel slowing down due to frictional torque; a see-saw with people of different masses.
Torque and rotational motion:
A force F applied at angle θ to a lever arm of length r produces torque τ = rF sinθ.
Electric Charge and Electric Force: Introduces electric charge and Coulomb’s Law.
Practice Electric Charge and Electric Force Problem Types:
These problem types involve electrostatic forces between point charges at rest in vacuum or air.
Two point charges fixed in space repelling or attracting each other; three charges arranged in a line with net force on one of the charge; two identical charged spheres hanging from strings and repelling at an angle; a charge placed at the corner of a right triangle with other charges at the remaining corners; charged pith balls used in electrostatics demonstrations.
Electric force between like charges:
Two positive charges (+q₁ and +q₂) repel each other with equal-magnitude forces
along the line joining them, separated by distance r.
DC Circuits: Covers current, resistance, and Ohm’s Law.
Equations: $V = I R$, $P = I V$, $\displaystyle \sum V_{\text{loop}} = 0$, $\displaystyle \sum I_{\text{node}} = 0$

These problem types involve steady current flow in resistive circuits powered by batteries or power supplies.
A single resistor connected to a battery; resistors in series or parallel with a battery; a combination circuit with both series and parallel branches; a circuit with a switch that opens or closes to change current; a circuit with an ammeter or voltmeter correctly placed to measure current or voltage.
Simple DC series circuit:
Voltage V drives current I through a resistor R,
following Ohm’s Law V = IR, with uniform current throughout the loop.
Mechanical Waves and Sound: Explores properties of waves.
Equations: $v = f \lambda$, $I \propto \dfrac{1}{r^2}$
Practice Mechanical Waves and Sound Problem Types:
These problem types involve transverse or longitudinal waves traveling through a medium, including sound waves in air or on strings.

AP Physics 1 – Study Tips
1. Focus on Key Concepts
Master the core topics: kinematics, Newton’s Laws, energy conservation, momentum conservation, rotational motion, simple harmonic motion, and electrostatics. These form the foundation of nearly all AP Physics 1 problems.
2. Free-Body Diagrams (FBDs) Are Essential
Always draw a Free-Body Diagram when analyzing forces with Newton’s Laws. Include only forces acting on the object, labeled clearly (e.g., Fg, FN, f, Fapp).
FBDs are not needed for purely kinematic or energy-only problems (e.g., “find speed from height” with no forces asked).
3. Practice Kinematics Graphs
Be fluent in interpreting position–time, velocity–time, and acceleration–time graphs.
Know how to find:
• Displacement = area under v–t graph
• Velocity = slope of x–t graph
• Acceleration = slope of v–t graph
4. Know Your Equations – and When to Use Them
Understand the meaning behind equations like $\sum F = ma$, $v = v_0 + at$, and $\Delta x = v_0 t + \tfrac{1}{2} a t^2$ before plugging in numbers.
Use the symbols and forms provided on the official AP Physics 1 Equation Sheet (e.g., scalar form, $\Delta PE_g = mg\Delta h$).
5. Units and Significant Figures
Prefer SI units (meters, kilograms, seconds) in calculations to match the AP Equation Sheet and avoid errors.
If a problem uses other metric units (e.g., cm, g), you may keep them only if the entire calculation stays consistent.
However, convert to SI when using equations for force, energy, or momentum (e.g., $F = ma$, $KE = \tfrac{1}{2}mv^2$),
unless the question explicitly asks for the answer in the given units.
Always include units in your final answer. If the problem provides data in cm or g and asks for the answer in those units, it’s acceptable —
but never mix unit systems (e.g., don’t combine cm with m or g with kg in the same equation).
Report final answers with 2–3 significant figures unless the problem specifies otherwise.
Practice problems involving torque ($\tau = r F \sin\theta$), rotational dynamics ($\sum \tau = I \alpha$), and rolling without slipping.
Remember: $KE_{\text{rot}} = \tfrac{1}{2} I \omega^2$ (analogous to $\tfrac{1}{2} m v^2$).
7. Calculator Use and Setup
Use a scientific calculator you know well—don’t try a new one on exam day.
Practice unit conversions and trig functions (sin, cos, tan) in degree mode (AP Physics 1 uses degrees, not radians).
8. Experimental Design
Be familiar with standard labs: carts on tracks, pendulums, spring-mass systems, and torque balances.
Know how to:
• Identify independent, dependent, and controlled variables
• Write a clear, step-by-step procedure
• Predict outcomes using physics principles
• Analyze data and justify claims with evidence
Common FRQ tasks: design an experiment to verify conservation of momentum or determine g using a pendulum.
9. Manage Time on Exam Day
Multiple-Choice (50 Qs, 90 min): ~1.8 min per question. Skip hard ones; return later. Eliminate wrong choices first.
Free-Response (5 Qs, 90 min):
• Q1 (Experimental Design): ~25 min
• Q2 (Qualitative/Quantitative Translation): ~15 min
• Q3–Q5 (Short Answer): ~12–15 min each
Always write something—partial credit is generous for clear reasoning, even with math errors.
10. Prioritize Conceptual Understanding Over Math
AP Physics 1 is primarily conceptual. Focus on why phenomena occur, not just calculations.
Practice explaining in words: “The acceleration is zero because the net force is zero.”
In FRQs, use reasoning words: because, therefore, this shows that...
11. Review Past FRQs
Study real free-response questions and scoring guidelines at AP Central.
Common themes: energy bar charts, momentum conservation, static equilibrium, and wave properties.
12. Stay Calm and Trust Your Reasoning
The exam tests your ability to apply physics to new situations—not memorize specific problems.
If stuck, ask: “What core physics principle applies here?” Then connect it to a law, equation, or diagram.
