- 54. are formed by two rays (or lines) that begin at the same point or share the same endpoint.
Down
- 1. an object is the rate of change of its position with respect to a frame of reference, and is a function of time.
- 2. a vector quantity that is defined as the rate at which an object changes its velocity
