Fundamental interaction

Why do things fall and magnets stick?

Imagine you're holding a magnet and letting it go. It sticks to your fridge door. Why does it stick?

Gravity pulls objects towards each other, and magnets stick because of a force called magnetism. These forces are like invisible hands reaching out to make things stick or fall.

Example

A 1 kg magnet sticks to a fridge door with a force of about 0.1 Newtons.

Remember this

Gravity and magnetism are fundamental forces that explain falling objects and magnetic attraction.
