Gravity pulls the moon toward Earth
Why does a magnet stick to your fridge
what is a magnetic field interacts with a metal, causing attraction
What happens to an object's motion when unbalanced forces act on it?
what is it changes speed, direction or both.

what is the rocket moves forward.
Why are atoms mostly empty space
what is because electron orbit away from the nucleus and take up much weight.
How can you tell if a magnetic field is present?
What is by using a magnet or seeing how it affects an object.
How do electromagnets differ from regular magnets?
what are they require electricity to create a magnetic field.
