Magnetic vs. Gravitational vs. Electric Review

Front

What increases the magnitude of the magnetic force between two magnets?

Back

Decreasing the distance between the magnets

Front

If two objects are moved closer together, how does this affect their gravitational potential energy?

Back

It decreases

Front

What happens when opposite poles of two magnets are brought close to each other?

Back

They attract each other

Front

What happens to the gravitational potential energy of an object as it falls towards the Earth?

Back

It decreases

Front

What factor can increase the strength of the magnetic field around a magnet?

Back

Decreasing the distance between two magnets

Front

What is the effect on the gravitational potential energy of an object if it is moved to a higher elevation above the Earth's surface?

Back

It increases

Front

How does the direction of electric force fields around a negative charge compare to that around a positive charge?

Back

It is in the opposite direction

Front

When two magnets are placed end to end with their opposite poles facing each other, what happens to the magnetic force between them?

Back

It increases

Front

What will happen to the potential energy of the magnets as the N and S get close?

Back

decrease

Front

Which of these magnet pairs has the MOST magnetic potential energy? Options: the N/S at the top because they are close, the S/S at the bottom because they are close, they both have the same amount

Back

the S/S at the bottom because they are close
