Momentum and Newton's Laws Quiz

What is the formula for momentum?

• p = m × v

• p = m / v

• p = m + v

• p = m - v

In a perfectly inelastic collision, what happens to the objects after the collision?

• They stop moving

• They stick together

• They explode

• They bounce apart

What does the first law of Newton state about an object at rest?

• It will change direction

• It will remain at rest unless acted upon by a force

• It will start moving on its own

• It will eventually fall

Which of the following is true about elastic collisions?

• Kinetic energy is lost

• Momentum is not conserved

• Kinetic energy is conserved

• Objects stick together

If a car with a mass of 1200 kg experiences a net force of 3000 N, what is its acceleration?

• 1.5 m/s²

• 3.0 m/s²

• 2.0 m/s²

• 2.5 m/s²

What is the principle of conservation of momentum?

• Total momentum before interaction equals total momentum after interaction

• Momentum is always lost

• Momentum is irrelevant in collisions

• Momentum can be created

In an elastic collision, which of the following is true?

• Momentum is not conserved

• Kinetic energy is conserved

• Momentum is lost

What happens to kinetic energy in an inelastic collision?

• It is converted to potential energy

• It is lost as heat or sound

• It doubles

• It is fully conserved

According to Newton's third law, what occurs with every action?

• There is no reaction

• There is a reaction of equal magnitude in the same direction

• There is a reaction of equal magnitude in the opposite direction

• The reaction is always greater

What is the relationship between force, mass, and acceleration as per Newton's second law?

• F = m + a

• F = m - a

• F = m × a
