Gravity Reveiw

The strength of the force of gravity depends on what two variables

Mass and distance

If the distance increases between two objects, the strength of gravitational force

Decreases

If the mass of an object increases its gravitational force

Increases

Larger object have _____ gravity

More

What is the difference between mass and weight

Mass is the amount of matter that makes up a substance. Weight is the pull of gravity on an object.

Two students sitting next to each other on earth will not feel the gravitational force of the student. Why?

Because the force of gravity is less on Pluto, mass would not change

If you traveled to Pluto, which property would change? Mass or weight? Explain why.

Weight would change to be less because the force of gravity is less on Pluto, Mass would not change

As a spaceship moves farther away from earth, what happens to the gravitational interaction between the earth and the space craft?

The gravitational attraction decreases

If the mass of the s7n were smaller, similar to the size of mercury (our solar systems smallest planet), what would happen to the orbit of the earth

The earth would no longer orbit and it would travel in a a straight line away from the sun.
