An acceleration due to a change in direction is called a centripetal acceleration .

Acceleration is equal to ? v/ ? t. Velocity is a vector and there are two ways a vector can be changed: by changing magnitude or by changing direction. An acceleration due to a change in direction is called a centripetal acceleration. The equation is: a c = v t 2 /r.

Circular Motion

Circular Motion. Vocabulary for Circular Motion. Period(T): the time it takes for one rotation or revolution. Measured in seconds. Revolution: traveling about an external axis, kid on merry-go-round. Rotation: spinning about an internal axis, an ice skater spinning.

The Apple & the Moon

The Apple & the Moon. Isaac Newton realized that the motion of a falling apple and the motion of the Moon were both actually the same motion , caused by the same force - the gravitational force. Universal Gravitation.
