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)
