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 determines the strength of gravitational force between two objects?

Back

The strength of gravitational force is determined by the masses of the objects and the distance between them.

Front

What happens to the gravitational pull as the distance between two objects increases?

Back

The gravitational pull decreases.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity.

Front

How does gravity affect objects on Earth?

Back

Gravity pulls objects towards the center of the Earth, giving them weight.

Front

What is the relationship between mass and gravity?

Back

More massive objects exert a stronger gravitational pull.

Front

What is the gravitational force between two objects with equal mass?

Back

The gravitational force is equal and attractive, pulling both objects towards each other.

Front

What is the effect of gravity on a falling object?

Back

Gravity causes the object to accelerate downwards towards the Earth.

Front

What is the formula for calculating 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.
