False Statement: In elastic collision, kinetic energy during the collision is not conserved.
Explanation:
Elastic collision is a type of collision where the total kinetic energy of the system is conserved. During an elastic collision, the total momentum of the system is also conserved. This means that the momentum before the collision is equal to the momentum after the collision.
The other given statements are true:
- The coefficient of restitution of a collision between two Steel balls lies between 0 and 1: The coefficient of restitution is a measure of the elasticity of a collision between two objects. It is defined as the ratio of the relative velocity of separation to the relative velocity of approach between the objects. For an elastic collision, the coefficient of restitution is 1, and for an inelastic collision, it is less than 1 but greater than 0.
- The momentum of a ball colliding elastically with the floor is conserved: The momentum of the ball before the collision is equal to the momentum of the ball and the floor after the collision. This is because the floor exerts an equal and opposite force on the ball, which results in the conservation of momentum.
- In an oblique elastic collision between two identical bodies with initially one of them at rest, final velocities are perpendicular: In an oblique collision, the final velocities of the two bodies are perpendicular to each other. This is because the initial momentum of the system is conserved, and the final velocities must be such that the total momentum is conserved.
Therefore, the false statement is "In elastic collision, kinetic energy during the collision is not conserved."
