Newton's Law of Universal Gravitation

Front

What does 'Newtons' represent in physics?

Back

Force

Front

What is the relationship between the mass of an object and the gravitational force?

Back

Mass increase, gravitational force increase.

Front

What does the gravitational force depend on?

Back

Mass and distance.

Front

The force of gravity is directly proportional to which of the following?

Back

Mass.

Front

If one of two objects increases its mass, what happens to the gravitational pull between the two objects?

Back

Increases.

Front

What is Newton's Law of Universal Gravitation?

Back

It states that every point mass attracts every other point mass by a force pointing along the line intersecting both points.

Front

What is the formula for 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 of the two masses.

Front

What is the gravitational constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)^2.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.

Front

What happens to gravitational force if the distance is halved?

Back

The gravitational force increases by a factor of four.
