universal gravitation

Front

What is the Universal Gravitational Constant?

Back

The Universal Gravitational Constant is 6.67 x 10^-11 N*m^2/kg^2, a key value in the law of universal gravitation.

Front

What configuration results in the greatest gravitational force?

Back

Large masses close together result in the greatest gravitational force.

Front

What happens to gravitational force if one object's mass is doubled?

Back

The gravitational force between two objects doubles.

Front

What occurs if you jump through a hole drilled from the North Pole to the South Pole?

Back

You would move back and forth between the North and South Pole in simple harmonic motion.

Front

Where is the force of gravity on an object greatest?

Back

The force of gravity is greatest at the surface of the Earth.

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 their centers.

Front

What does 'r' represent in the gravitational force formula?

Back

In the gravitational force formula, 'r' represents the distance between the centers of two masses.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two masses increases.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force is directly proportional to the product of the masses involved.

Front

What happens to gravity at the center of the Earth?

Back

At the center of the Earth, the force of gravity is zero.
