Magnets
What the two magnetic poles are called.
What is north and south?
The force that attracts any two objects together.
A bar magnet
Permanent
Newton's Second Law states that force is equal to THIS x THIS
Mass X Acceleration
The area around a magnet that affects other things.
What is a magnetic field?
The two factors that affect how strong the force of gravity is.
What are Mass of objects and distance apart?
A paper clip
Temporary
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.
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.
The cardinal and intermediate directions on a compass
What are North, South, East, West, Northeast, Southeast, Northwest, Southwest?
The moon has less gravity than the Earth because...
What is, the moon is less dense (has less mass)?
Aluminum wire
not magnetic
What causes Earth's magnetic field?
Dynamo action (movement of liquid metals) in Earth's outer core.
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.
Where Earth's magnetic poles are located
What is the Arctic Ocean and Antarctica?
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.
The Earth
Permanent
The Laws of Motion were written by this scientist.
Sir Isaac Newton
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.
The two things magnets can do.
What are repel and attract?
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

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.)
What object in the universe has the strongest gravitational force?
