What force pulls objects down?
Gravity
What is a magnet?

What are non-contact forces?
Non-contact forces are invisible forces that can affect objects, materials, and substances.
What happens to opposite poles?
attract
What is gravity?
a non-contact force that pulls objects toward the ground.
What materials attract magnets?
iron, cobalt, or nickel
Give an example of a non-contact force
Magnetism, Electrostatic, gravity
What happens to like poles?
repel
How does gravity affect weight?
The more weight, the faster it moves down
What happens when you touch a magnet?
An object that can attract or repel certain materials.
How do non-contact forces work?
They exert a force even when the objects are not touching.
Where is magnetic force strongest?
The ends of the poles
Why do we stay on the ground?
Gravity pulls us down
What are the north and south poles?
The two ends of a magnet where the magnetic force is strongest.
What happens to non-contact forces with distance?
weaker force
Why do magnets attract or repel each other?
Opposite ends attract. Due to the interaction between their magnetic poles.
How does gravity change in space?
It is weaker in space, but still exists.
What are examples of magnetic materials?
Iron, cobalt, nickel, and some types of steel.
Can non-contact forces pass through materials?
only some
How can materials become magnetized?
By interacting with a magnet, which aligns their magnetic domains.
