Science Project on “Air Friction”, Project Experiment Topics on Flight, Motion & Friction for Class 8, 9, 10 and 12 Students.

Air Friction

Materials Required:

1. Two-inch square cloth
2. Some thread
3. Two small metal nuts of the same size
4. Modelling clay
5. Scissors
6. Proximity to a place of height.

You skin your knee, when you run and fall due to the force of gravity. If you are at a higher position, then you fall faster. Parachutes can save a pilot’s life, if his plane is in trouble.

A parachute uses the mechanism of air resistance and that stops a falling object from falling very hard on the ground.

Shrouds are the harness that are attached to the parachute. It is the same thing that the pilot puts on when using the parachute.

To know whether the length of the shrouds have any determining effect on the effectiveness of the parachute, make two such parachutes, with different shroud lengths and test them out.

With the help of an adult, cut out two 10-inch square pieces of cloth to make your parachutes. Now take a small nut and attach four pieces of thread of about 6 inches to it. In the same process, tie a 12-inch thread to another nut of the same size. The other ends of the threads should be tied to the corners of the cloth.

Now stand at a height, so that you can drop both the parachutes, like maybe the balcony or a flight of stairs.

Hold the parachutes, pinching them at the center, with the weight of the nails pulling them down.

Stretching your arms, let them both go simultaneously. Find out which reaches the ground faster.
