1c Momentum Quiz alevel edexcel

Momentum is defined as the:

• Force acting on an object

• Mass of an object times its velocity

• Acceleration of an object

• Energy stored in an object

In an explosion, the total momentum of the system:

• Increases

• Decreases

• Remains constant

• Depends on the direction of the explosion

Conservation of linear momentum states that:

• Momentum is always conserved in collisions between objects

• Momentum is only conserved in elastic collisions

• Momentum is not conserved in explosions

• Momentum is conserved only in one-dimensional motion

Newton's third law states that:

• Every action has an equal and opposite reaction

• Force equals mass times acceleration

• Momentum is conserved in all collisions

• Energy cannot be created or destroyed

According to Newton's second law, the rate of change of momentum of an object is equal to:

• Its mass times its acceleration

• Its velocity divided by its mass

• Its force divided by its mass

• Its velocity squared
