* Gravity: The Earth's gravity pulls you towards it, even though you're not touching the ground. This force keeps you on the ground and makes objects fall.
* Magnetism: Magnets exert a force on each other, even when they're not physically touching. This is why magnets can stick to a refrigerator or attract metal objects.
* Electrostatic force: Charged objects can attract or repel each other, even when they are not touching. This is what makes your hair stand on end when you rub a balloon on your head.
* Electromagnetic force: This force is responsible for the interaction of electrically charged particles. It's what holds atoms together and is responsible for things like light, radio waves, and electricity.
In these examples, the forces are mediated by fields. For example, gravity is caused by a gravitational field, magnetism by a magnetic field, and electrostatic force by an electric field. These fields extend outward from the objects, and it's through these fields that the forces are exerted.
