In elastic collision:
Correct answer: C. Both a and b
- A. Kinetic Energy (K.E.) is conserved
- B. Momentum is conserved
- C. Both a and b
- D. None of these
Explanation
In an elastic collision:a) Kinetic Energy (K.E.) is conserved: This means that the total kinetic energy of the system before the collision is equal to the total kinetic energy of the system after the collision.b) Momentum is conserved: This means that the total momentum of the system before the collision is equal to the total momentum of the system after the collision.

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.
