Question 1

1.

Which of the following best describes the conservation of momentum in a system with no net external force acting on it?

A) The momentum of each object in the system remains the same.

B) The total momentum of the system before and after an event is constant

C) The momentum of the system increases due to the absence of external forces.

D) Momentum can only be conserved if the objects are stationary.

Question 2

2.

In a closed system with no net external forces, two objects collide. What happens to the total momentum of the system?

A) The total momentum is lost during the collision.

B) The total momentum is conserved; it remains the same before and after the collision.

C) The total momentum is zero after the collision.

D) The total momentum depends on the mass of the objects involved.

Question 3

3.

A car and a truck are moving toward each other, and they collide. If there are no external forces acting on the system, what happens to the momentum of the system?

The system’s momentum is transferred to the surrounding air.

The system’s total momentum is destroyed in the collision.

The momentum of the truck will be completely transferred to the car.

The system’s total momentum is conserved, meaning it remains the same before and after the collision.

Question 4

4.

Which of the following situations demonstrates the conservation of momentum in a system with no net external forces?

A) A rocket accelerates in space by expelling gas.

B) A soccer ball is kicked, and it accelerates across the field.

C) Two ice skaters push off each other and glide in opposite directions.

D) A car is moving uphill against gravity.
