Law of Universal Gravitation

Front

What is the Law of Universal Gravitation?

Back

The Law of Universal Gravitation 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.

Front

What two factors affect the magnitude of the gravitational force between two objects?

Back

Mass and distance.

Front

Why does a person weigh less on top of a mountain?

Back

Because they are farther from the center of the Earth, which reduces the gravitational force acting on them.

Front

Which of the following is NOT a result of gravitational attraction?

Back

The number of stars.

Front

What is gravitational attraction responsible for?

Back

The formation of planets, the orbit of planets, and the motion of stars.

Front

How does mass affect gravitational force?

Back

Greater mass results in a stronger gravitational force between two objects.

Front

How does distance affect gravitational force?

Back

As the distance between two objects increases, the gravitational force between them decreases.

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

The gravitational constant (G) is approximately 6.674 × 10^-11 N(m/kg)^2.

Front

What happens to gravitational force if the distance is halved?

Back

The gravitational force increases by a factor of four.
