Explain magnetic force and how magnets attract/repel without touching.
Some forces can push or pull an object without ever making physical contact. These are known as non-contact forces.
Explain static charges and electrostatic force.
Have you ever rubbed a balloon against your hair and watched the hair stand up? This invisible pull is called electrostatic force.
Explain gravity as a strictly attractive non-contact force.
Why does a ball always fall back down after you throw it in the air? The Earth constantly pulls objects towards itself using gravitational force, commonly known as gravity.
Match the scenario to the correct non-contact force.
