Question
An object moves in a circular path at a constant speed. Compare the direction of the object’s velocity and centrifugal force.
- Both are in the same direction
- Both are in opposite direction
- Both are perpendicular to each other
- Incomplete information
Hint:
The velocity at any point in a uniform circular motion is given by tangent to that point in the direction of motion
The correct answer is: Both are perpendicular to each other
The centrifugal force is a fictitious force. This force is assumed by an observer moving along the body in a circular motion to act in the direction away from the centre of circular path.
The velocity at any point in a uniform circular motion is given by tangent to that point in the direction of motion .
So they are perpendicular to each other
