- period
- the time needed to complete one cycle of motion

- equilbrium
- when the net sum of the forces acting on an object is zero

- coefficient of friction
- the ration of the force of kinitic friction to the normal force

- torque
- the product of force and lever arm

- uniform circular motion
- the movement of an object or a point mass at a constant speed around a cricle with a fixed radious

- normal force
- a constant force that acts perpendicular to and away from a serface

- projectile
- an object that has been launched with an intital thrust

- centripital accleration
- accleration towards the center of a circle

- centripital force
- the froce that acts toward the center of the circle

- flight time
- the time that the projectile is in the air

- trajectory
- a path of a projectile

- range
- the horizontal distance trevelled by a projectile

- level arm
- tge perpendicular distance from the axis of rotation to a line along which a force acts

- equilibrant
- a force that produces equilbrium

- maximum height
- the height of a projectile when its verticle velocity is zero

- rigid rotating object
- a mass that rotates around its own axis
