Question

How is the acceleration of an object in uniform circular motion constant?
A. in magnitude only
B.
in direction only
C.in both magnitude and direction
D.
in magnitude, direction, and orientation

Answer 1

In both magnitude and direction since acceleration is a vector quantity

Answer 2

Answer:

C. in both magnitude and direction

Explanation:

Circular motion is the movement of a body rotating around an axis along a circular path of constant radius. This movement can be uniform, if the speed of rotation is constant, or varied, if its speed changes over time. When an object moves in a circular motion, the speed is constant in magnitude and direction.

The circular movement occurs when a force of constant modulus is applied in a direction perpendicular to the speed of a piece of furniture, so that the modulus of this velocity remains constant, changing only its direction and its direction. The force applied in this case is called the centripetal force.
