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.

What is gravitational force?

Back

Gravitational force is the attractive force between two masses. It depends on the masses of the objects and the distance between them.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases. Specifically, it is inversely proportional to the square of the distance.

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 of the two masses.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (W = m * g).

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Front

How does mass affect gravitational force?

Back

Gravitational force increases with the mass of the objects involved. More massive objects exert a stronger gravitational pull.

Front

What happens to gravitational force if the distance is tripled?

Back

If the distance between two objects is tripled, the gravitational force becomes one-ninth (1/9) of the original force.

Front

Why do satellites stay in orbit around Earth?

Back

Satellites stay in orbit because they are moving forward at a speed that matches the curvature of the Earth, falling towards it but never hitting it.

What is the gravitational force on Jupiter compared to Earth?

Back

The gravitational force on Jupiter is more than twice that of Earth, meaning objects weigh significantly more on Jupiter.
