Energy is invisible yet it’s all around us and throughout the universe. We use it every day, we have it in our bodies and some of it comes from other planets! Energy can never be made or destroyed, but its form can be converted and changed.

Top of Page Top of Page Catapults and Elastic energy conversion in fleas and archery-from FT Exploring How fleas, catapults, and some other devices and animals, use energy storage mechanisms to improve performance. A poorly thought out demo of this page's subject.

All of the energy that the person used to pull the string back is now stored in the elastic material of the bow. Energy stored like this is called potential energy. The bow is made of elastic springy material that is good at storing and releasing energy. 2.

The following chapters describe the various forms energy can take and the story behind humans, energy, fuel and the environment. Types of energy. First let’s take a look at the different forms energy can take and how they can be converted. Kinetic-Anything that moves has this kind of energy. To run, cycle, climb and move the mouse for a computer we use kinetic energy. Radiant-Radiant energy means light.

Energy is one of the most fundamental parts of our universe. We use energy to do work. Energy lights our cities. Energy powers our vehicles, trains, planes and rockets. Energy warms our homes, cooks our food, plays our music, gives us pictures on television. Energy powers machinery in factories and tractors on a farm. Energy from the sun gives us light during the day.

As the slingshot is pulled back, chemical energy is transferred from David's muscles to elastic energy in the bands of the slingshot. After the slingshot is released, the elastic energy is transferred to the stone as energy of motion (kinetic energy). You can generate maximum energy and maximum speed by using a light stone and strong bands.

After the slingshot is released, it is assumed that all of the stored elastic energy is transferred to the stone as kinetic energy. The kinetic energy of the stone is related to both its mass and speed (). As a result, light stones shot from a slingshot move faster, but both light and heavy stones carry the same kinetic energy.

1. In the first drawing the flea's leg is cocked. The flea uses his leg muscles to bend the femur up against the coxa. Inside the coxa is a pad of resilin. The elastic resilin stores the muscle energy just like the bow stores human muscle energy. A trigger device in the leg keeps the leg bent.

Everything we do is connected to energy in one form or another. Energy is defined as: the ability to do work.. When we eat, our bodies transform the energy stored in the food into energy to do work.

We have made three key assumptions: 1. All of the energy stored in the elastic bands is transferred to the stone as kinetic energy. In fact, the elastic bands themselves gain speed and some kinetic energy. In most cases, the stone carries away essentially all of the elastic energy.
