Question

A skydiver jumps from an airplane, opens his parachute and after a while starts falling at a constant speed'. a) Define Drag b) Identify the direction of drag in the following scenario.

Answer 1

Explanation:

Another interesting force in everyday life is the force of drag on an object when it is moving in a fluid (either a gas or a liquid). You feel the drag force when you move your hand through water. You might also feel it if you move your hand during a strong wind. The faster you move your hand, the harder it is to move. You feel a smaller drag force when you tilt your hand so only the side goes through the air—you have decreased the area of your hand that faces the direction of motion.
