Forces on a Parachute
LO: to explain how changes in forces on a parachute effect it’s
speed
TASK: friction stories
Remember the bigger force should have a bigger arrow

ParachutesA parachute slows a falling
person from 120mph to 10mph so they can land safely.
How do you think a parachute achieves this (think about the last few lessons)

Can you explain the forces on the
parachute? (video)
Remember1.Unbalanced forces = accelerate or slows down.2.Balanced forces= steady (same) speed or stationary

Parachute testingWeigh an approximately 50g piece
of plasticine.Drop this from a height of 1.5m and
work out it’s speed. Do this 5 times and work out an average speed.
Construct a parachute for the plasticine and repeat the above, calculating an average speed.
