Question

When speed of body moving in straight line changes contnuously then the body acquirers?

Answer 1

The body acquires a certain speed at an instant. It may be a speed that's higher than the original one due to accelerating force or lesser than the original due to retarding force.

Remember, the acceleration or retardation may be uniform or non-uniform.

So, it's safe to say that the body acquires velocity/speed !! ; )

Answer 2

Answer:

when the speed of the body moving in a straight line changes continuously then the body acquires acceleration

Explanation:

because constant speed is known as velocity but in this case the speed is changing so it is acceleration
