Question

In a uniform circular motion ______.

Options

• speed of body continuously changes because the direction of motion changes

• velocity of body continuously changes because the direction of motion changes

• the motion of body is accelerated

• velocity of body continuously changes because the direction of motion changes and the motion of body is accelerated.

Answer 1

In a uniform circular motion velocity of body continuously changes because the direction of motion changes.

Explanation:

In a uniform circular motion, the speed of the body remains constant, but its direction of motion changes continuously at every point along the circular path. Since velocity depends on both magnitude (speed) and direction, a continuous change in direction means the velocity changes continuously.
