Gravity

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

True or False: An object with mass has gravity.

Back

True

Front

What is the law of universal gravitation?

Back

The law of universal gravitation states that every point mass attracts every other point mass 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.

Front

Who is credited with the law of universal gravitation?

Back

Isaac Newton.

Front

When will the forces of gravity between two objects be the greatest?

Back

When the masses of both objects are large and the objects are close together.

Front

What factors affect the strength of gravitational attraction?

Back

The strength of gravitational attraction depends on the masses of the objects and the distance between them.

Front

What happens to gravitational force if the distance between two objects increases?

Back

The gravitational force decreases as the distance between the two objects increases.

Front

What happens to gravitational force if the mass of one object increases?

Back

The gravitational force increases if the mass of one object increases.

Front

What is the gravitational force between two objects with small masses and far apart?

Back

The gravitational force is very weak.

Front

What is the gravitational force between two objects with large masses and close together?

Back

The gravitational force is very strong.
