Skydiving

The video explains how air resistance, a type of friction, affects a skydiver's descent. Initially, a skydiver falls due to gravity, with minimal air resistance due to a small surface area. As they fall, air resistance increases until it balances with gravity, reaching terminal velocity. When the parachute opens, the surface area increases, creating more air resistance, slowing the skydiver to a new, slower terminal velocity, allowing for a safe landing.

What is the role of air resistance when a skydiver jumps out of a plane?

Explain how the surface area of a skydiver affects air resistance during free fall.

What happens to a skydiver's speed when the forces of gravity and air resistance become balanced?

What is terminal velocity and how does it relate to a skydiver's descent?

Describe the changes that occur when a parachute opens during a skydive.
