Question

Constant force is required on the body for it to do circular motion.justify the statement

Answer 1

Answer:

Constant force is required in circular motion because direction is changing continously .

Explanation:

whenever a body change its direction , its velocity also changes but magnitude of the velocity of the body may be constant . As velocity is a vector quantity who has both magnitude and direction . So changing the direction of the body changes its velocity . whenever there is a change is velocity , there must be accleration and

Force = mass × accleration .
