 * Speed- distance an object travels per unit time **


 * Formulas- v=speed d=distance t=time **

Circular Motion Cenripetal Force- force that causes an object to follow a circular path

Speed

 Linear Speed- distance/speed Tangential Speed- speed along a circular path



__Linear Speed:__Distance/Time __Tangential Speed:__ Speed along a circular path __Rotational Speed__: number of rotations per unit of time. __Centripetal Acceleration__: Force that causes an object to follow a circular path
 * __ Rational Speed __**

Friction


 * //__static friction force__//**- opposite in direction to your force, and equal in force

__//**kinetic friction force**//__- is the force exerted on are surrface by the other when the surfaces are in relative motionCe
