forces - acting on a skydiver

Question 1

when the skydiver jumps out the plane, what force is acting on it

Answer 1

only weight due to gravity

Question 2

why does the skydiver accelerate towards the ground

Answer 2

because of weight, the skydiver receives a resultant force acting downwards

Question 3

what does the skydiver experience as they fall

Answer 3

friction with air molecules which is known as air resistance

Question 4

what direction does air resistance work in

Answer 4

upwards

Question 5

even after experiencing air resistance, why does the skydiver still accelerate downwards

Answer 5

the weight is still greater then the air resistance

Question 6

as velocity increases….

Answer 6

air resistance also increases

Question 7

at a certain point, the air resistance balances the weight, what does this mean

Answer 7

there is no resultant force so the velocity stays constant

Question 8

what has the skydiver now reached

Answer 8

terminal velocity

Question 9

what happens when the skydiver releases their parachute

Answer 9

surface area increases, meaning the air resistance also increases

Question 10

why does the skydiver decelerate

Answer 10

the air resistance is greater then th weight resulting in an upward force

Question 11

why would the resultant force become 0

Answer 11

because as velocity decreases so does air resistance meaning at some point it would equal the weight
