Momentum and Collisions Quiz

What is the formula for momentum?

• Velocity divided by mass

• Mass plus velocity

• Mass divided by velocity

• Mass times velocity

According to the conservation of momentum, what happens to the total momentum after a collision?

• It doubles

• It halves

• It becomes zero

• It remains the same as before the collision

In a collision between two cars, if one car is moving at 3 m/s and the other at 6 m/s, what is the total momentum before the collision?

• Cannot be determined

• 24 kg m/s

• 18 kg m/s

• 9 kg m/s

What happens when two objects collide and stick together?

• They explode

• They stop moving

• They move with a combined velocity

• They move with different velocities

In the example where two objects stick together after a collision, what is the velocity of the combined mass?

• 3 m/s forward

• 3 m/s backward

• 6 m/s forward

• 6 m/s backward
