Enter the appropriate word(s) to complete the statement. (Choose from the words between parentheses) In a inelastic , elastic)-
collision, both momentum and kinetic energy are conserved
-

The correct option is;

Elastic

Explanation:

In an elastic collision, the initial kinetic energy of the system is equal to the final kinetic energy of the system, such that there is no loss in the net kinetic energy available at a specific time or stage in the system

Therefore, we have;

1/2·m₁·v₁₁² + 1/2·m₂·v₂₁² = 1/2·m₂·v₁₂² + 1/2·m₂·v₂₂²

From which we get;

m₁·v₁₁ + m₂·v₂₁ = m₂·v₁₂ + m₂·v₂₂

Which is indicates that the initial and momentum of the system is also conserved

Therefore, in an elastic collision, both momentum and kinetic energy are conserved.
