1 Forces and safety features
By Kimberly Wilson

2 Forces and falling objects
Gravity is the force pulling downwards Resistance is a force working against gravity to slow down falling objects

3 A Parachute A large surface area and a parachute help to create resistance against gravity and slow a falling object down.

4 Car safety features and Shock absorbtion
Crumple zones and air bags act as shock absorbers taking most of the force in an accident instead of a human. Seat belts also help to prevent injury.

5 Other design factors Shape – which would fall faster? Why?
The helicopter has most of its weight towards the bottom. Why?
