Skydiving Forces and Terminal Velocity

The video tutorial explains the forces acting on a skydiver during free fall and parachute deployment. Initially, only weight acts on the skydiver, causing acceleration. As velocity increases, air resistance grows until it balances weight, reaching terminal velocity. Upon parachute deployment, air resistance surpasses weight, causing deceleration and a new, lower terminal velocity. The video also covers representing this motion on a velocity-time graph and provides additional resources for exam preparation.

What is the primary force acting on a skydiver immediately after they jump from the plane?

• Weight due to gravity

• Lift

• Thrust

• Air resistance

As a skydiver's velocity increases, what happens to the air resistance?

• It disappears

• It decreases

• It remains constant

• It increases

What is the term used to describe the constant velocity reached when air resistance equals weight?

• Balanced velocity

• Equilibrium velocity

• Terminal velocity

• Maximum velocity

Why does a skydiver open their parachute?

• To increase speed

• To increase air resistance

• To decrease air resistance

• To increase weight

What happens to the skydiver's velocity after the parachute is opened?

• It fluctuates

• It decreases

• It increases

• It remains constant

After the parachute is deployed, what is the relationship between air resistance and weight?

• Air resistance is greater than weight

• Air resistance is less than weight

• Air resistance is negligible

• Air resistance is equal to weight

What is the final velocity called when the skydiver is descending safely with the parachute open?

• Safe velocity

• Parachute velocity

• Lower terminal velocity

• Initial velocity

What happens to air resistance as the skydiver's velocity decreases after the parachute is opened?

• It decreases

• It remains constant

• It becomes zero

• It increases

At what point does the skydiver reach a lower terminal velocity?

• When air resistance equals weight

• When the parachute is closed

• When air resistance is greater than weight

• When air resistance is less than weight

What is the main reason for the skydiver to reach a lower terminal velocity?

• To increase weight

• To decrease air resistance

• To ensure a safe landing

• To increase speed
