Its acceleration may be decreasing

Vedclass · Answer

(B) If the speed of a body is increasing,the acceleration must be in the same direction as the velocity.However,the magnitude of acceleration does not necessarily have to be constant or positive.For example,if a particle moves in the positive direction with velocity $v > 0$,and its acceleration $a$ is positive and decreasing (e.g.,$a = 2 - t$),the speed will still increase as long as $a > 0$.Similarly,if a particle moves in the negative direction with velocity $v Therefore,the acceleration can be positive or negative,and its magnitude can be decreasing while the speed is increasing.

If a particle is moving along a straight line with increasing speed,then:
