The law of conservation of momentum states that:

• Momentum is always increasing

• Momentum is transferred but never created or destroyed

• Momentum decreases in closed systems

• Momentum is only conserved when external forces act

What is a closed system in physics?

• A system where mass and energy are exchanged with the surroundings

• A system where only energy is exchanged with the surroundings

• A system where neither mass nor energy is exchanged with the surroundings

• A system where external forces act

What happens in an inelastic collision?

• Objects bounce back without losing kinetic energy

• Objects stick together, and some kinetic energy is lost

• Both objects are destroyed

• Energy is completely conserved

What happens in an elastic collision?

• Objects lose all kinetic energy

• Objects stick together and move as one

• Objects bounce back with no loss of kinetic energy

• Objects slow down but don't stick together

What does Newton’s 3rd Law of Motion state?

• For every action, there is an equal and opposite reaction

• An object in motion stays in motion unless acted on by a force

• Force is equal to mass times acceleration

• Energy cannot be created or destroyed

In Newton’s 3rd Law, what is the action force?

• The force that an object exerts on another object

• The force that causes objects to accelerate

• The force that resists motion

• The total energy in a system
