If Earth's mass was cut in half, what would happen to your mass?

• increase because the gravitational force from Earth decreases

• decrease because the gravitational force from Earth decreases

• decrease because the gravitational force from Earth increases

• it would not change, my mass is not affected by gravitational force

Two objects can have both a gravitational attraction and an electrostatic repulsion.

• True, if the objects have the same charge and have mass

• True, if the objects have mass but were attracted and not repelling

• False, charged particles have almost no mass

• False, one field will cancel out the other

If every thing with mass has gravity, why does my cell phone not "stick" to me from gravity?

• My mass is so small, the gravitational field does not extend past my body.

• My cell phone's mass is too small to have gravity.

• My cell phone is electronic and has an electrostatic field that cancels out the gravitational field.

• My cell phone is not magnetic.

What type of force is gravity (select all that apply)?

• a non-contact force

• an repulsive force

• a weak force

• an attractive force

• a strong force
