Question
The direction of centripetal acceleration is always ____ the circular path.
- Away from the center of
- Towards the center of
- Along the tangent to
- None of these
Hint:
An object is able to maintain a circular orbit due to force from the body around which it is orbiting.
The correct answer is: Towards the center of
For an object moving in uniform circular motion, the change of direction gives rise to acceleration of the object. Due to inertia of the object, its velocity tries to move it along a straight path but it is maintained in its orbit due to centrifugal force of attraction. The resultant of these forces, called centripetal acceleration, is always pointed towards the center of the curvature.
