Newton's Law of Universal Gravitation

Front

What is Newton's Law of Universal Gravitation?

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

What happens to the pull of gravity as the distance between two objects increases?

Back

The pull of gravity decreases.

Front

What two factors determine the gravity between two objects?

Back

Mass and distance.

Front

What remains constant regardless of the gravitational field?

Back

Mass.

Front

When is the force of gravity between two objects the greatest?

Back

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

Front

True or False: Every object in the universe attracts every other object.

Back

True.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force increases with greater mass.

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, and r is the distance between the centers.

Front

What is weight?

Back

Weight is the force of gravity acting on an object, which depends on the object's mass and the gravitational field strength.

Front

How does gravity affect objects in space?

Back

Gravity keeps planets in orbit around stars and moons in orbit around planets.
