Question

What is the procedure for the experiment- study the various instances of transformation of energy you see around

Answer 1

Energy Transformations

An energy transformation is the change of energy from one form to another. Energy transformations occur everywhere every second of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical. Because the law of conservation of energy states that energy is always conserved in the universe and simply changes from one form to another, many energy transformations are taking place constantly.

Examples of Energy Transformations:

1. A toaster transforms electrical energy into thermal energy.

2. A blender transforms electrical energy into mechanical energy.

3. The sun transforms nuclear energy into ultraviolet, infrared, and gamma energy all forms of electromagnetic energy.

4. Our bodies convert chemical energy from food into mechanical and electrical energy to allow us to move.

5. A natural gas stove converts chemical energy from burning into thermal energy used to cook food.

TRANSFER OF ENERGY SCIENCE EXPERIMENT

February 8, 2019 by Sarah 17 Comments

Grab some marbles!  This simple science experiment is such an easy and fascinating way to demonstrate how energy is transferred from one object to another.

Energy is defined as the ability to do work.  We learned about the difference between potential energy (stored energy), and kinetic energy (the energy of moving things).  Our ping pong ball shooters were the perfect thing to learn about potential and kinetic energy!  When you stretch the balloons, they have potential energy, and when you release them, they have kinetic energy which they transfer to the ping pong balls, thus shooting it across the room.

Then we did an experiment to further study the transfer of energy from one object to another.

For this experiment, all you need is a ruler with a groove in the middle and some marbles.

First, we lined up three marbles in the middle and one marble at the edge.  I asked the boys what they thought would happen when I flicked the marble.  They thought that the marbles in the middle would roll away.



Surprise!  Only one of the marbles rolled away!

We repeated the experiment with different configurations of marbles (like shooting 2 at 3), and pretty soon the pattern emerged:  the number of marbles that you flick equals the number of marbles that roll away.  In other words, the rolling marble can only transfers its energy to the marble it collides with, which transfers the energy to the next marble, and so on.
