What is a Force?
5/10
📖 Explanation
Non-Contact Forces
Some forces act at a distance — no touching required!
🌍
Gravity
Pulls all objects with mass toward each other. Earth's gravity keeps you on the ground and the Moon in orbit.
🧲
Magnetic Force
Attracts or repels magnetic materials. Compass needles point north because of Earth's magnetic field.
⚡
Electric Force
Attracts or repels charged objects. Static electricity makes your hair stand up!
These forces seem almost magical — they work through empty space!
