What force balances the downward force of gravity before the skydiver jumps?
What force balances the downward force of gravity before the skydiver jumps?
- The skydiver's weight
- Air resistance
- Friction with the air
- The floor of the plane (correct)
What happens when the upward force of the air equals the downward force of gravity?
What happens when the upward force of the air equals the downward force of gravity?
- The skydiver stops falling
- Air resistance becomes negligible
- The skydiver accelerates further
- Forces are balanced and speed remains constant (correct)
Why does the skydiver slow down when the parachute opens?
Why does the skydiver slow down when the parachute opens?
- Air resistance suddenly becomes much greater than gravity (correct)
- Gravity increases significantly
- The skydiver's weight decreases
- The parachute exerts a stronger downward force
