📘 Definition

Air resistance is the force of air that pushes against an object when it moves through the air and slows it down.

📌 Main Details

It acts in the opposite direction of motion.

It is also called drag.

The faster an object moves, the stronger the air resistance.

Bigger objects face more air resistance.

Shape matters — smooth shapes have less air resistance.

It affects falling objects, vehicles, and flying objects.

🧠 Examples

When you run fast, you feel air pushing against you.

A feather falls slowly because air pushes against it.

A parachute slows down a skydiver.

Cyclists bend forward to reduce air resistance.

Airplanes are shaped smoothly to move easily through air.

⭐ Interesting Points

Sports cars are designed to reduce air resistance.

Birds spread their wings to increase air resistance when landing.

Space has no air, so there is no air resistance there.

Air resistance helps control the speed of falling objects.

🎉 Fun Fact

If there were no air resistance on Earth, a feather and a stone would fall to the ground at exactly the same speed.
