Universal Law of gravitation - E Block

Front

Who is credited with the law of universal gravitation?

Back

Newton

Front

If two asteroids exert a gravitational force, F, on each other and are moved to three times their original distance apart, what is the new gravitational force?

Back

F/9

Front

What does the law of universal gravitation state?

Back

Every object in the universe attracts every other object.

Front

What happens to the gravitational force between two planets as the distance between them increases?

Back

The gravitational force decreases.

Front

What is the relationship between the force of gravity and distance?

Back

The force of gravity is inversely proportional to the distance.

Front

What is the formula for the gravitational force between two masses?

Back

F = G * (m1 * m2) / r^2, where G is the gravitational constant.

Front

What does the variable 'r' represent in the gravitational force formula?

Back

The distance between the centers of the two masses.

Front

What is the gravitational constant (G)?

Back

G is approximately 6.674 × 10^-11 N(m/kg)^2.

Front

How does mass affect gravitational force?

Back

Gravitational force increases with greater mass.

Front

What is the effect of doubling the distance between two objects on the gravitational force?

Back

The gravitational force becomes one-fourth of its original value.
