Question

In Elastic Collisions, Both Momentum and Kinetic Energy Are Conserved.

A. True
B. False
C. Depends on the masses
D. Only in one-dimensional collisions

Answer 1

In Elastic Collisions, both momentum and kinetic energy are conserved.

Step-by-step explanation:

The statement 'In Elastic Collisions, Both Momentum and Kinetic Energy Are Conserved' is True.

In an elastic collision, both momentum and kinetic energy are conserved. This means that the total momentum and the total kinetic energy of the system remain constant before and after the collision.

For example, in a one-dimensional collision between two identical billiard balls, if one is initially motionless and the other moves with a certain speed, after the collision, the moving ball becomes stationary and the initially stationary ball moves with the same speed as the other originally had. This conservation of momentum and kinetic energy can be mathematically shown using the principles of physics.
