... Now, the amount of a physical quantity remains the same, no matter what system of units is used to obtain a numerical measure of that quantity. For instance, we might measure the length of an (American) football field with a meter stick and a yard stick. We’d get two different numerical values, but ...

Circular Motion Acceleration and Centripetal Force
... An object in uniform circular motion must experience an unbalanced force pointing towards the center of the circle. This force is referred to as a centripetal force, where centripetal means inward seeking . This force is required to cause the object to continually change its direction in order to mo ...
