Circular and Satellite Motion - Mission CG1 Detailed Help

TRUE     or     FALSE:
An object can move in a circle at a constant speed and still have a changing velocity.
(NOTE: Your actual true-false statement is selected at random from a collection of choices and may differ from the above.)

Definition of Acceleration:
The acceleration of an object is the rate at which the object changes its velocity.

Accelerating objects are changing their velocity. Velocity is often thought of as an object's speed with a direction. Thus, objects that are accelerating are either speeding up, slowing down or changing directions. Changing the velocity in any one of these three ways would be an example of an accelerated motion. A car could be moving in a circle and have a speedometer reading that remains constant at 25 mi/hr. However, the direction which the car is moving is changing. This change in direction means that the car is changing its velocity.
