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 does gravity do to objects?

Back

Gravity causes objects to pull towards one another.

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

What remains constant in different gravitational fields?

Back

Mass remains constant regardless of the gravitational field.

Front

True or False: Gravity attracts all objects towards one another.

Back

True.

Front

If a brick and a pencil are dropped from the same height, which will hit the ground first?

Back

Both will hit at the same time.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force increases with the mass of the objects.

Front

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

Back

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

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 exerted by gravity on an object, calculated as mass times the acceleration due to gravity.
