1.	Man needs power in various tasks like fire to cook food and electricity to move the fan etc. What are such means of power called
Answer» Answer: 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. For example, the chemical energy we GET from our food turns into kinetic and thermal energy (see below) when we walk and sound energy when we shout. Here’s a great video by SCIENTISTS showing the MANY ways that energy can be transferred and converted. Explanation:
