Use the drop-down menus to answer each question. which line represents the movement of a cart with a constant acceleration? a which line represents the movement of a cart with a constant velocity? c which lines represents a cart with no velocity or acceleration? b

Constant acceleration- A

Constant velocity- C

No velocity or acceleration- B

Explanation:

For body moving with a constant acceleration, the rate of change of displacement changes over time. This is proven by the increasing gradient of the curve (A) against time.

A body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient C.

A stationary body  covers no displacement as time elapses. thus the flat line with  zero gradient.
