Momentum and Conservation Quiz

What is the primary factor that distinguishes momentum from inertia?

• Momentum includes velocity, while inertia does not.

• Inertia includes velocity, while momentum does not.

• Momentum is a scalar quantity, while inertia is a vector.

• Inertia is measured in kilograms, while momentum is measured in meters per second.

How is momentum calculated?

• Velocity minus mass

• Mass divided by velocity

• Mass times velocity

• Velocity divided by mass

Which symbol is used to represent momentum in equations?

• P

• V

• M

• N

What is the unit of momentum?

• Meters per second squared

• Joules

• Newtons

• Kilograms times meters per second

In a hit and bounce scenario, what happens to the objects involved?

• They come to a complete stop.

• They stick together and move as one.

• They explode into multiple pieces.

• They bounce off each other with separate velocities.

In an explosion event, what happens to the momentum of the system?

• It becomes zero.

• It remains constant.

• It decreases.

• It increases.

According to Newton's third law, what happens when you push against a wall?

• Both you and the wall move in the same direction.

• Neither you nor the wall move.

• The wall moves in the opposite direction.

• You move in the opposite direction.

What is an example of Newton's third law in action?

• A car accelerating on a road.

• A book resting on a table.

• A person pushing off a boat and moving in the opposite direction.

• A ball rolling down a hill.

What is the main difference between elastic and inelastic collisions?

• Inelastic collisions involve explosions, while elastic involve sticking.

• Elastic collisions conserve kinetic energy, while inelastic do not.

• Elastic collisions involve explosions, while inelastic involve sticking.

• Inelastic collisions conserve kinetic energy, while elastic do not.

In an inelastic collision, what typically happens to some of the kinetic energy?

• It is lost as heat or sound.

• It is doubled.

• It is converted into potential energy.

• It is completely conserved.
