Correct answer is B
Momentum and kinetic energy are conversed in elastic collision
The property of a body to remain at rest or to continue to move in a straight line is known as
force
Impulse
Energy
Inertia
Correct answer is D
Inertia: the property of a body that resists any change to its uniform motion, equivalent to its mass
