Product Description
Video and lesson investigations on the topic of parachutes and air resistance. Key concepts include:
- Objects fall to Earth.
- Parachutes are designed to allow the human body and other objects to fall to the Earth slowly. Jumping without a parachute from an aeroplane would be a disaster.
- Parachutes are very unstreamlined.
- They increase air resistance and decrease the rate of fall.
- Making model parachutes and dropping them is a good way of experimenting with air resistance.
- Objects fall through air to the ground by the force of gravity acting on them. At the same time that gravity is pulling the falling object downwards, the air through which the object is falling is pushing upwards.
- The more air that can be captured by the falling object, the slower will be its fall toward the Earth.
