Newton's Law of Universal Gravitation

Front

What is Newton's Law of Universal Gravitation?

Back

It states that every mass attracts every other 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

True or False: Gravity only affects large objects like planets.

Back

False. Gravity affects all objects with mass.

Front

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

Back

The gravitational pull decreases.

Front

What is the relationship between mass and gravitational attraction?

Back

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

Front

When is the gravitational attraction between two objects the least?

Back

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

Front

What is an example of gravity in everyday life?

Back

An example is when an apple falls from a tree to the ground.

Front

What is the effect of gravity on the moon?

Back

The moon has gravity, which is why it can hold onto its atmosphere and cause tides on Earth.

Front

How does gravity affect the motion of planets?

Back

Gravity keeps planets in orbit around the sun.

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.
