Question
The velocity is always _______ to the line of a circle along which an object is moving.
- Outwards
- Towards the center
- Tangential
- Faster
Hint:
Velocity has both magnitude and direction as it is a vector quantity.
The correct answer is: Tangential
The velocity is always tangential because circular motion is a special case of curved motion. For any curved path the instantaneous velocity is in a direction tangent to the curve.
