According to the video, what two factors determine the size or pull of gravity?

Mass of the objects and distance between them.

Explain the difference between mass and weight as described in the video.

Mass is the amount of matter in an object and remains constant. Weight is the measure of gravitational force on an object and can change depending on the gravitational pull.

Why do planets revolve around the sun, according to the video?

The sun has a much larger mass than the planets, resulting in a greater gravitational force that pulls or attracts the planets towards it.

Learning Objective

I can describe and calculate the gravitational force between two objects using Newton's Law of Universal Gravitation.

1
Gravity is a force that attracts objects toward each other, keeping planets in orbit around the sun.
2
The strength of gravity depends on an object's mass; the greater the mass, the greater the gravitational force.
3
Two scientists who made important discoveries about gravity are Sir Isaac Newton and Albert Einstein.
