Gravitational Force - Test Review

Front

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

Back

Air resistance.

Front

What do we call data that supports or disputes a scientific idea?

Back

Evidence.

Front

If Jupiter has about 317 times more mass than Earth, what can we infer about its gravitational force?

Back

Jupiter’s gravitational force is much stronger than Earth’s gravitational force.

Front

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

Back

True.

Front

True or False: Gravity keeps the Earth in orbit around the sun.

Back

True.

Front

What is gravity?

Back

A force that attracts two bodies towards each other.

Front

What is the relationship between mass and gravitational force?

Back

More mass means a stronger gravitational force.

Front

What is the effect of air resistance on a falling object?

Back

It slows down the object's fall.

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 their centers.

Front

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

Back

The gravitational force decreases.
