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 = rF
Linear to Rotational Conversions
x = rθ
v=rω
a=rα
Rotational Kinematics
∆θ = ωit + ½αt²
ω = ωi + αt
ω² = ωi² + 2α∆θ
 
Rotational Momentum
L = Iω
K = ½Iω²
∆L= τ∆t
 

Momentum

When Momentum is Conversed:
∑pi = ∑pf
 
p = mv
∆p = F∆t or J = F∆t
Elastic Collision (KE conserved, p conserved)
m1v1 + m2v2 = m1v3 + m2v4
 

Momentum

When Momentum is Conversed:
∑pi = ∑pf f
