MECHANICS : MOTION - Conservation of Linear Momentum
What happens when two objects collide and their total kinetic energy is conserved?
It is an inelastic collision.
It is an elastic collision.
The objects stick together.
Momentum is not conserved.
What is the result of an explosion in a system where momentum is conserved?
The system loses mass.
The total momentum remains the same.
The total kinetic energy increases.
The objects combine into a single mass.
If two ice skaters push off from each other, what happens to their total momentum?
It increases.
It decreases.
It becomes zero.
It remains the same.
Which of the following situations is a real-life application of the conservation of linear momentum?
