Momentum and Conservation Quiz

What is the primary focus of this video in the series on momentum?

• Conservation of energy

• Kinetic energy

• Conservation of momentum

• Newton's laws of motion

According to Newton's Third Law, what happens when two objects collide?

• One object exerts a greater force

• No forces are exerted

• They exert equal and opposite forces on each other

• They exert forces in the same direction

What is impulse defined as in the context of momentum?

• The sum of forces

• The difference in mass

• The product of force and time

• The change in velocity

In a collision, if object one experiences a leftward impulse, what happens to object two?

• It experiences no impulse

• It experiences a rightward impulse

• It experiences a leftward impulse

• It experiences a downward impulse

What remains constant in a system where two objects collide and only exert forces on each other?

• Total energy

• Total momentum

• Individual momentum

• Total mass

What does the law of conservation of momentum state about the total momentum in an isolated system?

• It can be destroyed

• It remains constant

• It can decrease

• It can increase

Which of the following is NOT a conserved quantity in physics?

• Energy

• Momentum

• Velocity

• Mass

In a problem-solving scenario, if a 5 kg cart moving at 5 m/s collides with a 2 kg cart moving at 2 m/s, what is the total initial momentum?

• 25 Newton seconds

• 15 Newton seconds

• 10 Newton seconds

• 21 Newton seconds

After a collision, if a 5 kg cart is moving at 1 m/s, what is the velocity of a 2 kg cart?

• 1 m/s

• 8 m/s

• 5 m/s

• 3 m/s

When a 15 kg mass is dropped onto a 5 kg cart moving at 2 m/s, what is the new velocity of the cart?

• 3 m/s

• 1 m/s

• 0.5 m/s

• 2 m/s
