Force and parachute
1. Fill in the missing gaps in the sentences. Then match them up
with the pictures of a skydiver who has just jumped out of ar
aeroplane.

A. She opens her parachute. There is a very
resistance force so she starts to

The skydiver only has the downward force of her

. it is
As she accelerates faster, the resistance force

as her weight. She now moves at a
speed because the
force acting on her is zero. She is now at her
velocity(She cannot go any faster)
As she decelerates the air resistance force on her parachute
until it is the
size as her weight.
She is now moving with a
speed until she hits the
ground - a new, slower
velocity
2. Now draw arrows to represent the different forces acting on the
skydiver and label them with the types of force. Make the length
of your arrow show the size of the force i. e a long arrow represent
a large force.
pls help..
