100

What the two magnetic poles are called.

What is north and south?

100

The force that attracts any two objects together.

What is gravity?
100

A bar magnet

Permanent

100

Newton's Second Law states that force is equal to THIS x THIS

Mass X Acceleration

What keeps harmful particles from the Sun from hitting our planet?
Our magnetic field
200

The area around a magnet that affects other things.

What is a magnetic field?

200

The two factors that affect how strong the force of gravity is.

What are Mass of objects and distance apart?

200

A paper clip

Temporary

200

A golf ball rolls down a ramp and hits a cup. The cup slides across the table. What happened to the energy in the golf ball?

It was transferred to the cup when they collided.

200

What causes the seasons?

The tilt of Earth's axis causes more direct sunlight to hit our region in the summer and indirect sunlight in the winter. 

300

The cardinal and intermediate directions on a compass


What are North, South, East, West, Northeast, Southeast, Northwest, Southwest?

300

The moon has less gravity than the Earth because...

What is, the moon is less dense (has less mass)?

300

Aluminum wire

not magnetic

300

What causes Earth's magnetic field?

Dynamo action (movement of liquid metals) in Earth's outer core.

300

What keeps objects in our orbit in the same position?

Their speed keeps them from being pulled into the Earth, but gravity keeps them from flying out into space.

400

Where Earth's magnetic poles are located

What is the Arctic Ocean and Antarctica?

400

There are two objects the exact same size sitting on a table. Object A has a mass of 10 kg and object B has a mass of 5 kg. Which object has a great gravitational attraction?

Object A because it has more mass.

400

The Earth

Permanent

400

The Laws of Motion were written by this scientist.

Sir Isaac Newton

400

Why do the planets in our solar system orbit the Sun?

The Sun is a star and has so much mass that all the planets are pulled in by its gravitational force.

500

The two things magnets can do.

What are repel and attract?

500

Why are we more attracted to the Sun rather than a huge planet like Jupiter?

The Sun has more mass than Jupiter AND it is closer to us than Jupiter

500

Staples

temporary

500

What is inertia?

An objects resistance to a change in movement (an object at rest stays at rest, and object in motion stays in motion.)

500

What object in the universe has the strongest gravitational force?

What is a black hole?
