Law of Gravitation

Front

What are the two factors affecting the magnitude of the force of gravity between two objects?

Back

Mass and distance.

Front

What is the value of the Universal Gravitational constant?

Back

6.673X10^-11 Nm^2 kg^-2.

Front

According to Newton, what happens between any two masses?

Back

They attract each other.

Front

How does the gravitational attraction between the Earth and the Moon compare?

Back

The same force as the Moon attracts the Earth.

Front

If the gravitational force between two bodies is F, what happens to the force if one mass increases by 2x?

Back

The force becomes 2F.

Front

What is the formula for Newton's law of gravitation?

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 their centers.

Front

What does the gravitational constant (G) represent?

Back

It represents the strength of the gravitational force in the universe.

Front

How does distance affect gravitational force?

Back

As distance increases, the gravitational force decreases.

Front

What is the relationship between mass and gravitational force?

Back

Greater mass results in a stronger gravitational force.

Front

What is the significance of the gravitational force in the universe?

Back

It governs the motion of planets, stars, galaxies, and even light.
