For Inquiry, our theme has been 'How Stuff Works'. We have been researching information and planning to make our own parachutes. Here are few pictures of us testing our parachutes and also some information we found out.
How do
Parachutes Work?
A
parachute is a device used to slow down an object that is falling towards the
ground.
There
are two forces acting on the falling person:
1. Gravity (Upwards)
2.
Air
resistance (Downwards)
Without
a parachute, the gravity is more than air resistance. However, as the parachute
opens, the air resistance increases. Now, air resistance is more than gravity.
This
slows down the parachute and the person or object can land safely on the ground.
Here are some of the wonderful plans that students put together:
