Conservation of Momentum Concepts

What does the conservation of momentum state about a closed system?

• The total momentum changes over time.

• The total momentum remains constant.

• The total momentum increases over time.

• The total momentum decreases over time.

In a collision between two objects of equal mass, what happens to the total momentum?

• It doubles.

• It halves.

• It remains the same.

• It becomes zero.

What happens to the total momentum when two objects collide and move in different directions?

• It remains constant.

• It becomes zero.

• It decreases.

• It increases.

How does the conservation of momentum apply to objects moving at different speeds?

• The momentum is transferred to the environment.

• The faster object loses all its momentum.

• The slower object gains all the momentum.

• The total momentum of the system remains constant.

What happens to the momentum of a stationary object when another object collides with it?

• It remains stationary.

• It loses momentum.

• It gains momentum.

• It transfers momentum to the environment.

If two objects collide and stick together, how is the velocity of the combined object determined?

• It is the sum of their initial velocities.

• It is double the velocity of the initially moving object.

• It is half the velocity of the initially moving object.

• It is the average of their initial velocities.

What is the effect of conservation of momentum on the speed of combined objects after sticking together?

• The speed halves.

• The speed doubles.

• The speed becomes zero.

• The speed remains the same.

Why is it challenging to move around the ISS without a handhold?

• Because of the lack of air resistance.

• Due to the absence of gravity.

• Due to the presence of strong magnetic fields.

• Because the total momentum must remain constant.

In a zero-gravity environment, why can't you move by wiggling or swimming?

• Because there is no air to push against.

• Because the friction is too high.

• Because the total momentum of the system must remain constant.

• Because the gravity is too strong.

How does conservation of momentum affect movement in space?

• It increases the speed of movement.

• It has no effect on movement.

• It makes movement challenging without external forces.

• It allows for easy movement without effort.
