Which is an example of a non-contact force?

Explanation:
Non-contact forces act on objects without needing to touch them. Gravity fits this idea because it pulls objects toward each other through space, so you can feel the pull even when there’s no physical contact. Friction and normal force require surfaces to touch, since they arise from contact interactions. Magnetic force can act at a distance as well, but in this context gravity is the clear example of a non-contact force because its influence is felt across space without contact.
