Universal Gravity Concepts

Front

What is Universal Gravity?

Back

Universal Gravity is the force of attraction between two masses, which is 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 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 does the gravitational constant (G) represent?

Back

The gravitational constant (G) is a proportionality factor used in the calculation of gravitational force, approximately equal to 6.674 × 10^-11 N(m/kg)^2.

Front

How does mass affect gravitational force?

Back

More mass results in a stronger gravitational force; as the mass of either object increases, the gravitational attraction between them increases.

Front

How does distance affect gravitational force?

Back

As the distance between two objects increases, the gravitational force decreases; specifically, it is inversely proportional to the square of the distance.

Front

What is the SI unit of force?

Back

The SI unit of force is the newton (N).

Front

What happens to gravitational force if the distance is halved?

Back

If the distance between two objects is halved, the gravitational force increases by a factor of four, since force is inversely proportional to the square of the distance.

Front

What is the relationship between gravitational force and the mass of objects?

Back

Gravitational force is directly proportional to the product of the masses of the two objects; if either mass increases, the gravitational force increases.

Front

What is the effect of increasing both masses on gravitational attraction?

Back

Increasing both masses will increase the gravitational attraction between them, as gravitational force depends on the product of the two masses.

Front

When is gravitational force at its minimum?

Back

Gravitational force is at its minimum when the masses of both objects are small and the objects are far apart.
