What is the Law of Conservation of Momentum?

Momentum is transferred during a collision

Momentum is not affected by collisions

Momentum is gained or lost during a collision

Momentum is doubled during a collision

What is the difference between balanced and unbalanced forces?

Balanced forces are equal in size and opposite in direction, while unbalanced forces are not

Balanced forces have a net force of 0 N, while unbalanced forces have a net force of 1 N

Balanced forces cause a change in motion, while unbalanced forces do not

Balanced forces are always greater than unbalanced forces

Melanie is accelerating as she skates on the ice. However, the speed at which she is skating has not changed. A possible explanation for this is that Melanie

is changing directions as she skates in a circle

has reached the top speed at which she can skate

has stopped skating and is now standing still

On a roller coaster, the cars first climb a hill at a decreasing speed. Then the cars speed up as they go down the hill, before coasting at a constant speed on a straight track. Finally, the cars slow down as the ride ends. The cars have zero acceleration while

slowing down at the end of the ride

Which of the laws of motion states, "To every action there is an equal but opposite reaction"?

Law of Conservation of Momentum

Acceleration describes

How much force is needed to change an object's motion

How much velocity changes in a given amount of time

The tendency of an object to resist a change in motion

The balanced forces on a falling object with a constant speed

Rank the following objects from the least amount of inertia to most inertia

Carl and Juan are playing catch. Carl throws a fastball to Juan and it hurts Juan's hand. Why is this the case?

Greater the acceleration, the greater the force

Greater the mass, greater the acceleration

Greater the acceleration, the less the force

Greater the mass, the less the force

A person is on a paddleboard. The person exerts a force on the water with the paddle, causing hte water to move. The paddleboard also moves, but ni hte opposite direction. Which statement best explains why this happens?

Law of Conservation of Momentum

A person steps out of the boat and onto the dock. As the person moves forward onto the dock, the boat moves backward. Which statement best describes the backward motion of the boat as the person steps forward?

For every action there is an equal and opposite reaction.

Every mass exerts a force on every other mass.

An object at rest tends to stay at rest.

Friction opposes the motion of an object.

A person not paying attention while skateboarding hits a rock. The skateboard stops...they didn't.

The Law of Conservation of Momentum

The Law of Universal Gravitation

What is the difference between distance and displacement?

Distance is the force exerted on an object, while displacement is the momentum of the object.

Distance is the rate of change of velocity, while displacement is the resistance to a change in motion.

Distance is the speed of an object, while displacement is the direction of its motion.

Distance is how far an object has moved, while displacement is the difference in starting and ending point.
