True or False: A magnet is attracting when it pushes objects away from each other.
a)
True
b)
False
2.
A child puts two magnetic toy trains next to each other on a track. What will happen next, and why?
a)
The trains will not move.
b)
The trains will move away from each other.
c)
The trains will move closer to each other.
d)
Not enough information.
3.
A child sets identical magnetic carts on tracks. At the end of each track is a large magnetic train that cannot move. The child uses her hand to slide the carts on each track. Which of these movements will result in the greatest decrease in potential energy?
a)
Moving the cart on Track A one space to the left <
b)
Moving the cart on Track B one space to the left <
c)
Moving the cart on Track B one space to the right >
d)
These movements each have the same change in potential energy because they each move the car the same distance.
4.
A train engineer is working with two identical magnetic roller coaster cars on different sides of a center magnet that cannot move. The engineer can only move one car one space. Which movement will result in the largest increase in potential energy?
a)
Moving the blue car one space toward the center magnet.
b)
Moving the green car one space away from the center magnet.
c)
Moving the green car one space toward the center magnet.
d)
These movements each have the same change in potential energy because they move the roller coaster car the same distance.

19.
A child moves a magnet towards another magnet that cannot move. What happens to the potential energy in the system of magnets?
a)
Potential energy decreases because the blue magnet train moves in the same direction as the magnetic force.
b)
Potential energy decreases because the blue magnet train moves against the magnetic force.
c)
Potential energy increases because the blue magnet train moves against a magnetic force.
d)
Potential energy does not change because the magnets in the system do not change.
