Front

What are the two factors that affect the force of gravity?

Back

Mass and Distance.

Front

Which scientist is known for explaining that gravity causes planets to orbit the Sun?

Back

Newton.

Front

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

Back

Gravity decreases.

Front

What is the term for the amount of matter in an object?

Back

Mass.

Front

What determines the gravitational force between two objects?

Back

The mass of the objects and the distance between them.

Front

What is gravity?

Back

A force that attracts two bodies towards each other.

Front

How does mass affect gravity?

Back

Greater mass results in a stronger gravitational pull.

Front

What is the relationship between distance and gravitational force?

Back

As distance increases, gravitational force decreases.

Front

Who formulated the laws of planetary motion?

Back

Kepler.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.
