Question 13

Describe what happens when a man jumps out of a plane

Answer 13

1) The skydiver jumps out the plane
2) as she accelerates faster the air resistance force and acts in the opposite way to her weight
3) the air resistance force increases until it is the same as her weight she is now moving at a constant speed it’s called her terminal velocity.
4) opens the parachute, now not a large air resistance force so she starts to decelerate.
5) the air resistance force decreases until it’s the same size as her weight. Falling at constant speed it’s called terminal velocity.
6) on the ground her weight is now equal to the upward force form the ground the forces unbalanced!
