Science Project on “Stored Energy”, Project Experiment Topics on Energy in Different Forms for Class 8, 9, 10 and 12 Students.
Stored Energy
Materials required:
- Two 2-litre plastic bottles
- Books
- One Ruler
- Two boards (1 inch x 4 inch)
- Water
- An adult
Potential energy is usually defined as the contained energy of an object to move it upto a height, as the gravitational pull will cause it to move downwards. Two objects of different weights will have different potential energy levels to move.
For the experiment, stack several books on the floor, thereby raising them to the same height of about one foot. Create ramps with the help of the books, by placing each end of the ramps on them. You can use shelf boards for the ramps. However, if you don’t have any such boards, you can take the help of an adult to cut two similar boards from a piece of plywood.
Now fill one end of the bottles with water and screw the cap on tightly, to avoid any leakage. The other bottle should remain empty. Now place each bottle on each ramp respectively. The heavier bottle will move faster than the lighter one when you let them both go simultaneously. The bottle that goes further will contain more potential energy than the other bottle.
This proves the essence of momentum or the force that moves an object. Momentum is calculated as the mass of an object multiplied with its velocity and this makes it more difficult to stop heavier objects quickly.
