Gravitational Force - Test Review

Front

What is the friction between the air and a moving object called?

Back

Air resistance.

Front

Does an object with mass have gravity?

Back

True.

Front

True or False: Gravity exists between any two objects that have mass.

Back

True.

Front

What direction does gravity pull objects?

Back

Towards the center of the Earth.

Front

What is needed to move more massive objects against the pull of gravity?

Back

More force.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, proportional to their masses.

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 the gravitational constant (G)?

Back

Approximately 6.674 × 10^-11 N(m/kg)^2.

Front

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

Back

The gravitational force decreases.

Front

What is weight?

Back

The force exerted by gravity on an object, calculated as weight = mass × gravity.
