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 the force of gravity between two objects?

Back

F = G * (m1 * m2) / r², where F is the gravitational force, G is the universal 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 distance affect the force of gravity?

Back

The force of gravity is inversely proportional to the square of the distance between the centers of two objects; as distance increases, the gravitational force decreases.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the gravitational force acting on that mass.

Front

What is the actual weight of an object?

Back

The gravitational force acting upon a body caused by a planet or star.

Front

What is apparent weight?

Back

The psychological illusion of heaviness felt by an object, which can differ from its actual weight due to various factors.

Front

What does the term 'gravitational field' refer to?

Back

A region of space around a mass where another mass experiences a force of gravitational attraction.

Front

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

Back

It describes how the gravitational force decreases with the square of the distance between two masses.

Front

What would have the greatest gravitational pull on each other?

Back

Two large objects close together.
