Question

The body moves by acceleration acnnot move with regulat speed

Answer 1

Answer:

Yes,  

a body can have a constant speed and still be accelerating. Acceleration can be either due to change in speed or due to direction of motion or both. Consider an example of a uniform circular motion. In a circular motion, the body moves with a constant speed but we still say that it is accelerating due to the change in direction

This acceleration is called centripetal acceleration and is given as

ac =  v2/r

where v= constant speed

and r= radius of circle
