What is an important characteristic of uniform circular motion?

The direction of motion changes continuously with time.

Which force is responsible for maintaining uniform circular motion?

Centripetal force

If a car is stopped in 10 seconds by applying brakes with a retardation of 2.5 m/s^2, what is the initial velocity of the car?

25 m/s

Describe the motion of a body that is accelerating at a constant rate of 10 m/s^2.

The body's velocity increases by 10 m/s every second.

If a motorcycle is moving at 5 m/s and accelerates at 0.2 m/s^2 for 10 seconds, what is its final speed?

7 m/s
