A push or pull that changes how things move or their shape.

Using force to move something forward.

Using force to move something towards you.

Using force to move objects. Ex: Pushing a chair.

Using force to move objects. Ex: Pulling a door.

Materials that are attracted to magnets, like iron, nickel, and cobalt.

Materials that are not attracted to magnets, like plastic, wood, and glass.

Magnets can be used to separate magnetic materials from non-magnetic ones.

Magnets are used to create clasps for jewelry and other objects.

When two magnets are placed with their opposite poles facing each other, they will attract.

When two magnets are placed with their similar poles facing each other, they will repel and push away from each other.

A buildup of electric charge on a surface, often caused by rubbing objects together.

Atoms are made of protons (positive charge), neutrons (no charge), and electrons (negative charge).

Two objects with the same type of electrical charge will repel each other.

Two objects with different types of electrical charges will attract each other.

The rate at which an object changes its speed or direction.

The rate at which an object slows down.

A repeated movement of an object in a predictable pattern.

A force that opposes motion between two surfaces in contact.

The force that pulls all objects towards the center of the Earth.
