Gravity and Orbits

Front

Gravity pulls everything toward...

Back

The center of mass

Front

What are three things all planets have in common?

Back

Orbit the sun, massive enough that their gravity controls all objects in the area, and they are spherical.

Front

Why does Earth's surface bulge at the equator?

Back

Earth's rotation creates centrifugal force

Front

Gravity attracts all objects towards one another.

Back

True

Front

Does any object with mass have gravity?

Back

True

Front

As distance between two objects increase, the pull of gravity...

Back

Decreases

Front

Why would a person weigh less on the Moon than on the Earth?

Back

Moon has less mass and therefore less gravity

Front

Two factors affecting the magnitude of the force of gravity between 2 objects are...

Back

mass and distance

Front

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

Back

Nothing, mass is not affected by gravitational force.

Front

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

Back

decrease because gravitational force decreases
