Question

acceleration and velocity does not change abruptly at an instant as the changes are continuous

Answer 1

rate of change in velocity is directly proportional to acceleration

Answer 2

ANSWER:

Acceleration and velocity changes continuously and does not change abruptly. This is because we cannot move from the speed of 0 metre/second square to 20 metre/second square without reaching to 10 metre/second square. Therefore we can see that the changes are continuous not abrupt.

EXPLANATION:

Velocity is defined as the distance covered by a body in a particular duration of time. Acceleration is defined as the variation of velocity with time gradient. In simple word we can say that acceleration is the changing of speed while covering a distance with direction.

When a body is in rest its speed is equal to zero, then it starts to accelerate and reaches to any value which is a positive integer. In the course of reaching to a particular speed, the body has to cover all the speed which comes in between 0 and that particular speed, in a continuous manner and not abruptly.
