Question

what is the angle between velocity vector and acceleration vector in a uniform circular motion

Answer 1

Hi, This is the answer

When the object is moving in uniform circular motion, then the angle between the velocity vector and acceleration vector is equal to 90 degrees. In this case, the type of acceleration caused is generally called centripetal acceleration. Thus acceleration vector forms 90-degree angle with the velocity vector.

Answer 2

The angle between velocity vector and acceleration vector in a uniform circular motion is π/2

Detailed answer

This is because acceleration is always towards the center.

• During this state, the velocity is always along the tangential direction.
• This makes the angle between them as π/2 in all conditions.
• But there are some cases in which the angle formed between the velocity vector and acceleration vector during a circular motion is either obtuse or forms an acute angle.
• Acceleration that is in the direction of the center will cause the angle to phase to π/2
