The net acceleration of a particle in circular motion is:
Correct answer: A. Toward the centre
- A. Toward the centre
- B. Always along the radius
- C. Irregular
- D. Circular in motion
Explanation
The net acceleration of a particle in circular motion is directed toward the centre of the circular path. This type of acceleration is known as "centripetal acceleration." It is responsible for keeping the particle moving in a circular path and preventing it from moving in a straight line tangent to the circle. The centripetal acceleration is always directed radially inward and is essential for maintaining circular motion.

About Acceleration
Acceleration measures the rate at which velocity changes with time, including changes in speed, direction or both. Work includes average and instantaneous acceleration, the relation a = Δv/Δt, uniform acceleration equations, and interpreting velocity time and displacement time graphs, with acceleration carefully distinguished from velocity.
