This is the first set of equations for the AP Physics B exam.
Newtonian Mechanics

###
velocity with a, no x

v = v₀-at

###
position with a, no v

x = x₀+v₀t+½at²

###
velocity with a, no t

v²=v₀²+2a(x-x₀)

###
Centripetal Acceleration

a=v²/r

###
Change in Gravitational Potential Energy

ΔU=mgΔh

###
Work done by a force at an angle

W=FΔrcosθ

###
Power of an object in motion

P=Fvcosθ

###
Restoring force of a spring

F=-kx

###
Elastic Potential Energy

U=½kx²

###
Period of an object oscillating on a spring

T=2π√(m/k)

###
Period of a pendulum for small angles

T=2π√(l/g)

###
Period and frequency relationship

T=1/f

###
Newton's Universal Law of Gravitation

F=-(Gm₁m₂)/(r²)

###
Gravitational Potential Energy

U=-(Gm₁m₂)/(r)
