Two magnets are attracted to other.  One magnet is big and strong; the other is small and weak.  The big magnet attracts the small magnet with ____________________________.

• the same force with which the small magnet attracts the big magnet

• a stronger force than with which the small magnet attracts the big magnet

• a weaker force than with which the small magnet attracts the big magnet

Use the figure to answer this question.

What are the two forces acting on the upper magnet?

• the magnet's weight and the magnetic force attracting it to the lower magnet

• gravity and the magnetic force pushing it away from the lower magnet

• the upper magnet's weight and mass

Use the figure to answer this question.

What is the relationship between the force the lower magnet applies to the upper magnet and the force the upper magnet applies to the lower magnet?

• They are equal.

• They act in opposite directions.

• They get stronger as the magnets get closer to one another.

• All of the above.

A rocket in outer space is traveling toward a far-off planet.  

An astronaut turns on the rocket's engines, which exerts a force on the rocket.  

There is no gravity or air resistance.

While the engines are on, how will the rocket move?

• The rocket will move at a constant speed.

• The rocket will move only while the engines are on.

• The rocket will move faster and faster as long as the engines are on.

A rocket in outer space is traveling toward a far-off planet.  

An astronaut turns on the rocket's engines, which exerts a force on the rocket.  

There is no gravity or air resistance.

When the astronaut turns off the engines, what will the rocket do?

• 
  It will continue moving at a constant speed because no forces are acting upon it.

• 
  It will steadily slow down until the force from the engines is gone.

• It will steadily slow down because no forces are acting upon it.

A student pushes on a heavy rock, but it does not move.  

Why does the rock not move?

• The rock is heavier than the student.

• There must be another force on the rock, opposing the student's push.

• Nothing is moving, so there are no forces acting.

If object A feels an attractive force 420 N from object B,

what kind of force will object A feel if its mass is doubled?

• 210N

  (half of the force)

• 840N

  (double the force)

• 420N

  (equal force)
