Universal Gravitation

Front

What is the Law of Universal Gravitation?

Back

It states that every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases, specifically it is inversely proportional to the square of the distance.

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
