Unit 1: Forces and Gravity

Front

What happens to your mass if Earth's mass is cut in half?

Back

Nothing, mass is not affected by gravitational force.

Front

Acceleration occurs when an object changes its speed or ______.

Back

Direction.

Front

What happens to the force between two objects when you double the distance between them?

Back

The force becomes 1/4X.

Front

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

Back

Less.

Front

What is the SI unit for acceleration?

Back

m/s².

Front

Define gravitational force.

Back

The attractive force between two objects with mass.

Front

What is inertia?

Back

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

Front

State Newton's Second Law of Motion.

Back

Force equals mass times acceleration (F = ma).

Front

What is the relationship between mass and weight?

Back

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

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.
