Newton's Law of Universal Gravitation

Front

What is Newton's Law of Universal Gravitation?

Back

It 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 is the formula for calculating gravitational force?

Back

F = G * (m1 * m2) / r², where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.

Front

What is the value of the Universal Gravitation Constant (G)?

Back

6.67 x 10^-11 Nm²/kg².

Front

How does mass affect gravitational force?

Back

Increasing the mass of either object increases the gravitational pull between them.

Front

What is the gravitational field strength near the surface of the Earth?

Back

Approximately 9.81 m/s².

Front

What is the relationship between distance and gravitational force?

Back

Gravitational force decreases as the distance between two objects increases, following the inverse square law.

Front

What is the inverse square law in the context of gravitation?

Back

It states that the gravitational force between two masses is inversely proportional to the square of the distance between them.

Front

What is apparent weight?

Back

It is the weight that an object appears to have when subjected to acceleration, such as in an elevator.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What happens to gravitational force if the distance between two objects is halved?

Back

The gravitational force increases by a factor of four.
