Universal Gravitation Review

Front

What is the law of universal gravitation?

Back

The law of universal gravitation 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 happens to gravitational force if one mass is doubled?

Back

If one mass is doubled, the gravitational force between the two masses also doubles, assuming the distance remains constant.

Front

What happens to gravitational force if the distance between two masses is doubled?

Back

If the distance between two masses is doubled, the gravitational force decreases by a factor of four, since force is inversely proportional to the square of the distance.

Front

How is the distance (r) measured in gravitational calculations?

Back

The distance (r) is measured from the center of one mass to the center of the other mass.

Front

What is the effect on gravitational force if both masses are doubled?

Back

If both masses are doubled, the gravitational force increases by a factor of four, since force is proportional to the product of the masses.

Front

What is the formula for gravitational force?

Back

The formula for gravitational force is 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 masses.

Front

What is the gravitational constant (G)?

Back

The gravitational constant (G) is approximately 6.674 × 10^-11 N(m/kg)^2, and it is used in the calculation of gravitational force.

Front

If the gravitational force between two objects is 10 N, what will it be if one mass is halved?

Back

If one mass is halved, the gravitational force will also be halved, resulting in a force of 5 N, assuming the distance remains constant.

Front

What is the relationship between gravitational force and mass?

Back

Gravitational force is directly proportional to the masses of the objects involved; as mass increases, gravitational force increases.

Front

What is the relationship between gravitational force and distance?

Back

Gravitational force is inversely proportional to the square of the distance between the centers of the two masses; as distance increases, gravitational force decreases.
