AP Physics Cheat Sheet (DRAFT) by

Cheat sheet for AP Physics 1 2020

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Rotational Motion

τ_net= Iα
τ = r F sinθ
τ = r F
Linear to Rotational Conversions
x = rθ
Rotational Kinematics
∆θ = ωit + ½αt²
ω = ωi + αt
ω² = ωi² + 2α∆θ
Rotational Momentum
L = Iω
K = ½Iω²
∆L= τ∆t

Momentum (Linear)

When Momentum is Conversed:
∑pi = ∑pf
p = mv
∆p = F∆t or J = F∆t
pf = pi + J
Types of Collisions
Elastic Collision
KE conserved & momentum conserved
Bounce perfectly off each other
Inelastic Collision
KE lost & momentum conserved
Travel in same direction at different speeds
Perfectly Inelastic Collision
Greatest KE lost & momentum conserved
Objects coupled and travel in same direction
