A spaceship is traveling through space. Suddenly, its speed increases. What can you say about the kinetic energy of the spaceship?
The kinetic energy increases as its speed increases.
The kinetic energy decreases as it is converted into speed.
The kinetic energy remains the same because speed and kinetic energy are not related.
There is no way to know what happened to the kinetic energy.
A device that uses a free-moving magnetic needle to show direction is a:
Ruler
magnet
compass
magnetic field
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.
Pablo sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Pablo can move the carts one space to the left or one space to the right. Which movement will increase the potential energy in the system the most?
Moving the cart on Track 1 one space to the right (→).
Moving the cart on Track 1 one space to the left (←).
Moving the cart on Track 2 one space to the left (←).
All these movements will result in the same change in potential energy because they each move a cart the same distance.
An engineer is experimenting with two identical magnetic roller coaster cars on different sides of a center magnet that cannot move. For the experiment, 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.
Moving Car 2 one space away from the center magnet.
Moving Car 1 one space away from 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.
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.
