Orbit.

100

What is matter?

Anything that takes up space and has mass.

100

What happens when you drop an object?

It falls toward Earth.

200

What is gravitational pull?

The pull gravity has on an object.

200

Is a force a push, a pull, or both?

Both

200

What keeps the Moon close to Earth?

Gravity/gravitational force.

200

What is mass

The amount of matter in an object.

200

Why do objects fall toward Earth?

Because Earth’s gravity pulls it downward.

300

What is gravitational force?

The force of attraction between objects.

300

What force can slow down a falling object?

Air resistance.

300

What is rotation?

The spinning of an object on its axis.

300

A pulling force between objects.

300

400

Gravity is a force of ______ between objects.

Attraction

400

Give an example of a push and a pull.

Answers will vary.

400

What is revolution?

The movement of one object around another.

400

What is weight?

How much gravity pulls on an object.

400

How are mass and weight different?

Mass is the amount of matter; weight is how strongly gravity pulls on that mass.

500

Does gravity only exist on Earth? why?

No. Gravity exists between objects with mass.

500

Name two forces that can act on a falling object.

Gravity and air resistance.

500

Explain how gravity affects the Moon’s movement.

Earth’s gravity pulls the Moon toward Earth and helps keep it in orbit.

500

Explain the difference between gravitational force and gravitational pull.

gravitational force is the force itself, while gravitational pull describes its pulling effect.

500

Why doesn’t the Moon fly away from Earth?

Earth’s gravitational pull keeps the Moon moving around Earth instead of flying away.
