Question

An object moves in a circular path at a constant speed. What is the relationship between the directions of the object's velocity and acceleration vectors? (a)-The velocity and acceleration vectors point in opposite directions. (b)-The velocity and acceleration vectors are perpendicular. (c)-The velocity vector points in a direction tangent to the circular path. The acceleration is zero.
(d)-The velocity vector points toward the center of the circular path. The acceleration is zero. (e)-The velocity and acceleration vectors point in the same direction.

Answer 1

Answer:

b

Explanation:

When an object is in circular motion, the direction of velocity is in the direction of tangent to the circle and acceleration is always directed towards the radial direction. This means that velocity is always perpendicular to acceleration of the object.

Hence option  (b)-The velocity and acceleration vectors are perpendicular is correct.
