Ramon puts two magnetic toy trains very close to each other on a track. What will happen next, and why?
The trains will move closer to each other because the magnetic force will pull the trains together.
The trains will not move 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 move away from each other because the magnets are not touching.
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.
Based on the magnetic field line diagrams, what will happen next with these two sets of magnets?
The magnets in Set 1 will repel, and the magnets in Set 2 will attract
The magnets in Set 1 will attract, and the magnets in Set 2 will repel.
The magnets in Set 1 will not move, and the magnets in Set 2 will attract.
In both sets, the magnets will attract.
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 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.
The potential energy does not change because the magnets in the system do not change.
A spaceship is traveling through space. Suddenly, its kinetic energy decreases. What is most likely to be true about the speed of the spaceship?
The speed increases as the kinetic energy is converted into speed.
The speed decreases as the kinetic energy decreases.
The speed remains the same because speed and kinetic energy are not related.
The speed increases to make up for the decrease in kinetic energy.
How does magnetic force affect the energy in a system of magnets when the magnets are released and begin to move?
The magnetic force increases the potential energy in the system.
The magnetic force decreases the kinetic energy in the system.
The magnetic force changes kinetic energy into potential energy.
The magnetic force changes potential energy into kinetic energy.
