Product Description
Video and lesson investigations on the topic of gravity and air-resistance. Key concepts include:
- Objects fall through air to the ground.
- They fall downwards.
- The shape of an object makes a difference to the way in which it falls and the speed of its fall.
- 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.
- Air resistance causes drag and slows down unstreamlined shapes.
- The shape of an object make a difference in the way in which it falls and the speed of its fall
- Parachute are designed to catch air so that they can cause a human body and other objects to fall to Earth more slowly.
