Multiple Choice

Sharona puts two magnetic toy vehicles very close to each other. What will happen next, and why?

• The toy vehicles will not move because the magnets are not touching.

• The toy vehicles will move closer to each other because the magnetic force will pull the vehicles together.

• The toy vehicles will move away from each other because the magnets are not touching.

• The toy vehicles will move away from each other because the magnetic force will push the toy vehicles apart.

Multiple Choice

In a computer simulation, Jeffrey moves a magnet (Magnet 2) toward another magnet (Magnet 1) that cannot move. What happens to the potential energy in the system of magnets?

• The potential energy does not change because the magnets in the system do not change.

• The potential energy increases because Magnet 2 moves against the magnetic force.

• The potential energy decreases because Magnet 2 moves against the magnetic force.

• The potential energy decreases because Magnet 2 moves in the same direction as the magnetic force.

Multiple Choice

Kinetic energy can be described as

• the energy that is stored in an object or system.

• the energy stored in a skateboard at the top of a hill.

• the energy an object has because it is moving.

• the energy stored in the food you eat.

Multiple Choice

The space around an object in which magnetic forces can act on objects is known as

• its magnetic poles.

• the magnetic field.

• the attraction force.

• the force of repulsion.

Multiple Choice

Multiple Choice

The energy that is stored in an object or system is called

• kinetic energy.

• potential energy.

• calories.

• force.

Multiple Choice

The definition of repel is

• to provide evidence against a claim.

• to pull objects toward one another.

• a set of interacting parts forming a complex whole.

• to push objects away from each other.

Multiple Choice

To move from one object to another or place to another is known as

• transferring.

• exchanging.

• forcing.

• repelling.

Multiple Choice

If your are providing evidence that goes against a claim you are

• supporting the claim.

• researching a claim.

• refuting the claim.

• repelling the notion that someone could dare have an idea that is not in perfect alignment with what you, as a very logical person, knows to be true.

Multiple Choice

Ramon puts two magnetic toy trains very close to each other on a track. What will happen next, and why?

• The trains will move away from each other because the magnets are not touching.

• The trains will move away from each other because the magnetic force will push the trains apart.

• The trains will not move because the magnets are not touching.

• The trains will move closer to each other because the magnetic force will pull the trains together.

Multiple Choice

Based on the magnetic field line diagrams, what will happen next with these two sets of magnets?

• The magnets in Set 1 will attract, and the magnets in Set 2 will repel.

• In both sets, the magnets will attract.

• The magnets in Set 1 will repel, and the magnets in Set 2 will attract.

• The magnets in Set 1 will not move, and the magnets in Set 2 will attract.

Multiple Choice

Abdul moves a magnetic toy train away from a magnet that cannot move. What happens to the potential energy in the system of magnets during the movement?

• The potential energy does not change because the magnets in the system do not change.

• The potential energy decreases because the train moves in the same direction as the magnetic force.

• The potential energy decreases because the train moves against the magnetic force.

• The potential energy increases because the train moves against the magnetic force.

Multiple Choice

An engineer is investigating potential energy with two identical magnetic roller coaster cars on different sides of a center magnet that cannot move. To test her ideas, the engineer will move one car one space. Which movement will result in the largest increase in potential energy?

• Moving Car 2 one space toward the center magnet.

• All these movements will result in the same change in potential energy because they each move a roller coaster car the same distance.

• Moving Car 2 one space away from the center magnet.

• Moving Car 1 one space toward the center magnet.

Multiple Choice

A spaceship is traveling through space. Suddenly, its speed increases. What can you say about the kinetic energy of the spaceship?
