4-3 Newton's Universal Law of Gravity

Front

What is Newton's Universal Law of Gravity?

Back

It states that every point mass attracts every other point mass in the universe 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

How does mass affect gravitational force?

Back

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

Front

How does distance affect gravitational force?

Back

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

Front

What happens to a person's weight on the Moon compared to Earth?

Back

A person weighs less on the Moon because the Moon has less mass and therefore less gravity.

Front

What configuration results in the greatest gravitational force?

Back

Large masses that are close together.

Front

When is the gravitational force between two objects the least?

Back

When the masses of both objects are small and the objects are far apart.

Front

What is the relationship between distance and gravitational force?

Back

The farther away two objects are, the less gravitational force there is between them.

Front

Who is credited with the law of universal gravitation?

Back

Sir Isaac Newton.

Front

What is the formula for calculating gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.

Front

What is the gravitational constant (G)?

Back

G is a constant used in the calculation of gravitational force, approximately equal to 6.674 × 10^-11 N(m/kg)^2.
