Universal Gravitation

Front

What is gravitational force?

Back

A force that attracts any object.

Front

Complete the following statement: The farther away two planets are the _______ the gravitational force between them.

Back

Less.

Front

What are the two factors affecting the magnitude of the force of gravity between two objects?

Back

Mass and distance.

Front

The force of gravity is inversely proportional to which factor?

Back

Distance.

Front

If a man weighs 1000N on the surface of the Earth, how much will he weigh at twice the distance in the atmosphere?

Back

250 N.

Front

What is the formula for gravitational force between two masses?

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 the gravitational constant (G) represent?

Back

It is a proportionality factor used in the calculation of gravitational force.

Front

How does mass affect gravitational force?

Back

Greater mass results in a stronger gravitational force.

Front

How does distance affect gravitational force?

Back

As distance increases, gravitational force decreases.

Front

What is the relationship between weight and mass?

Back

Weight is the force of gravity acting on an object's mass.
