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)

### Acceleration Due To Gravity =

(Force Of Gravity) / (Mass)

(Mass)(Velocity)

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)

### 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)
