Equations to study for AP Exams

###
Average Velocity=

distance/time

###
Acceleration

Change in Velocity/Time

###
Final Velocity=

Initial Velocity + (acceleration)(time)

###
distance=

(initial velocity)(time) + (1/2)(acceleration)(time)²

###
Final Velocity²=

Initial Velocity² + (2)(Acceleration)(Distance)

###
Acceleration=

(Net Force) / (Mass)

###
Force Of Friction=

(µ)(Normal Force)

###
Force of Gravity=

(G)(mass1)(mass2) / (radius)²

###
Acceleration Due To Gravity =

(Force Of Gravity) / (Mass)

###
Momentum =

(Mass)(Velocity)

###
Momentum Before =

Momentum After

###
Impulse =

(Net Force)(Time) or (Change in Momentum) or (Mass)(Change in Velocity)

###
Force on A Spring =

(Spring Constant)(Change in Spring Length From the Equilibrium Position)

###
Potential Energy Stored By A Spring =

(1/2)(Spring Constant)(Change in Spring Length From the Equilibrium Postion)²

###
Centripetal Force =

(Mass)(Centripetal Acceleration) or (Mass)(Velocity)² / (Radius)

###
Centripetal Acceleration =

(Velocity)² / (Radius)

###
Change in Potential Energy =

(Mass)(Acceleration due to Gravity)(Change in Height)

###
Kinetic Energy =

(1/2)(Mass)(Velocity)²

###
Work =

(Force)(Distance) or (Change in Total Energy)

###
Total Energy =

(Potential Energy) + (Kinetic Energy) + (Internal Energy)

###
Power =

(Work) / (Time) or (Force)(Distance) / (Time) or (Force)(Average Velocity)
