Gravity and Orbits Review

Front

What are the two factors that affect the force of gravity between two objects?

Back

Mass and distance.

Front

What is the term for the time it takes a planet to go around the sun?

Back

Orbital period.

Front

What does gravity pull everything toward?

Back

The center of a mass.

Front

Why would you weigh less on Uranus than on Earth despite Uranus having more mass?

Back

Uranus has a much larger radius, so you are much farther from the center of mass.

Front

How does the force of the sun's gravitation pull change as you move away from the sun?

Back

It gets weaker.

Front

What is gravity?

Back

A force that attracts two bodies toward each other.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What is the effect of distance on gravitational force?

Back

The greater the distance between two objects, the weaker the gravitational force.

Front

What is an orbit?

Back

The path one object takes around another object due to gravity.

Front

What keeps the planets in orbit around the sun?

Back

The sun's gravitational pull.
