Electricity and Magnetism Review

Gravity is...

• the force of attraction between any two objects

• the force of attraction and repulsion between like and unlike poles

• any phenomenon associated with stationary or moving electrons,ions or other charged particles

• the force that attracts a body toward the center of the earth, or toward any other physical body having mass.

Where would an astronaut weigh less on, the moon or Earth?

• The moon, since it has less mass, it would have less gravity

• The earth, since it has a greater mass,it would have more gravity

• The moon, since it has a greater mass, it would have more gravity
