I WONDER- What Is Drag?

Drag is a force that opposes motion, making it difficult for objects to move through air. An example is running with a parachute, which fills with air and slows you down. The faster an object moves, the more drag it experiences. Skydivers increase their surface area to increase drag and slow down.
