Is the acceleration of a particle in circular motion not always towards the centre. Explain.

Text Solution

AI Generated Solution

To determine whether the acceleration of a particle in circular motion is always directed towards the center, we need to analyze the types of acceleration involved in circular motion. ### Step-by-Step Solution: 1. **Understanding Circular Motion**: - Circular motion refers to the movement of an object along the circumference of a circle. 2. **Types of Acceleration in Circular Motion**: ...
