Conservation of momentum: What is the principle of conservation of momentum?

Momentum is not conserved in a closed system

Total momentum of a closed system remains constant if no external forces act on it.

Momentum decreases with external forces

Momentum increases with external forces

Conservation of momentum: State the equation for the conservation of momentum in a closed system.

total initial momentum = total final momentum

total initial momentum = total kinetic energy

total initial momentum = total mass

total initial momentum = total initial velocity

Conservation of momentum: Explain how momentum is conserved in an isolated system.

Momentum is conserved only if the objects involved are at rest

Momentum is conserved only if the objects involved are in motion

Momentum is conserved only if the objects involved have the same mass

Momentum is conserved in an isolated system by ensuring that the total momentum before an event is equal to the total momentum after the event.

Conservation of momentum: A 2kg object moving at 4m/s collides with a stationary 3kg object. What is the velocity of the two objects after the collision?

The velocity of the 2kg object after the collision is 3 m/s, and the velocity of the 3kg object after the collision is 1 m/s.

The velocity of the 2kg object after the collision is 2 m/s, and the velocity of the 3kg object after the collision is 2 m/s.

The velocity of the 2kg object after the collision is 1.33 m/s, and the velocity of the 3kg object after the collision is 2 m/s.

The velocity of the 2kg object after the collision is 4 m/s, and the velocity of the 3kg object after the collision is 0 m/s.
