PhysicsLAB Uniform Circular Motion Centripetal Forces

In order for an object to travel in a circular path an unbalanced central force must be exerted upon it Otherwise the object would continue to travel along a straight line path based on its inertia. Typical sources of centripetal forces are tensions in strings friction banked curves and gravitation.

Velocity of a Falling Object Calculate with Examples

In every day use velocity is often used interchangeably with speed. However in calculus there is a significant difference between the two In mathematics speed refers to how fast an object travels Velocity however is defined as both the rate at which an object is traveling i.e how fast and its direction. In calculus it is the first derivative of the position function.
