Question

If a body is moving at constant speed in a circular path, its

a. velocity is constant and its acceleration is zero

b. velocity and acceleration are both changing direction only

c. velocity and acceleration are both increasing

d. velocity is constant and acceleration is changing direction​

Answer 1

Answer:

And since velocity is a vector that has both magnitude and direction, a change in either the magnitude or the direction constitutes a change in the velocity. For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating.

Answer 2

Answer:

d is correct

Explanation:

When a body is moving in a circular motion with constant speed, the direction of it continuously changes and hence velocity(v), momentum(p), and acceleration change because they are vectors and their direction changes.only as kinetic energy is a scalar, it remains constant
