Typical sources of centripetal forces are tensions in strings friction banked curves and gravitation.

Click to chatIn 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.
