PHYSICS FINAL CH6

The planet Jupiter is about 300 times as massive as Earth, yet on its surface you would weigh only about three times as much. This is because

Jupiter's radius is 10 times Earth's radius.

When the distance between two stars decreases by half, the force between them?

increases to four times as much

What is the force of gravity on a 500-N woman standing on Earth's surface?

500N

Earth's gravitational field extends?

both inside and outside Earth and throughout the entire universe

An object is placed exactly halfway between Earth and the Moon. The object will fall toward the?

earth

According to Newton, the greater the masses of interacting objects, the?

greater the gravitational force between them.

If the mass of Earth somehow increased with no change in radius, your weight would?

increase also

Consider two planets in space that gravitationally attract each other. If the masses of both planets is doubled, and the distance between them is also doubled, then the force between them is?

no change
