skydiver in free fall Flashcards
1
Q
what 2 forces does the skydiver experience?
A
weight and friction/ air resistance
2
Q
first step in the sky diver in free fall?
A
force of air resistance increases with speed
3
Q
3rd step of skydiver in free fall?
A
air resistance = weight and the forces become balanced- acceleration is 0 so he is travelling at terminal velocity
4
Q
fourth step of skydiver in free fall?
A
when skydiver opens the parachute there is an increase in air resistance
5
Q
5th step of skydiver in free fall?
A
air resistance is larger than weight and air resistance slows the acceleration meaning that the skydiver decelerates and the forces balance out again
