In a circular motion, the acceleration is always directed towards:
Correct answer: A. The centre
- A. The centre
- B. The tangent
- C. Between the tangent and the normal
- D. None of the above
Explanation
Centripetal acceleration (ac) in circular motion always points towards the center of rotation. This is because acceleration is in the direction of the change in velocity, which points directly towards the center of the circular path.Options B, C, and D are incorrect because they do not represent the correct direction of acceleration in circular motion.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
