energy in the world
energy is the ability to work. all things in the wolrd have energy. also with need energy to move. energy can be stored or in movement. electrical energy is an example of a light bulb. the fire has heat energy. when you do force you are working with your muscular energy. sunglight is an example of solar energy. energy can move water, that is called hydel energy. windmills produce electricity , that electricity works by the wind and is called wind energy. we don´t see energy but energy is in all parts of the world. if you move , you are giving a force that is energy. streching a rubber band has potential energy, that is energy store
people death
People are dying because doctors do not find the disease they have in time, which causes them to get sick and that the disease increased their risk. The solution is to invent an edible pill that inside has a camera to find out as soon as possible the illness of the person.This robot will save thousands of lives and will reduce deaths.

Types of Energy
Energy is all that cause work, We find energy different forms . When you eat, the body breaks down the food giving you energy, Another example is when you receives energy from the sun by radiation. The main founds of energy are kinetic and potential energy. Kinetic energy is the energy in motion for example: water falling over the fall. Potencial energy is the energy stored in an object example:water at the top of the waterfall. Energy cannot be created or destoyed but it can be transformed. Mechanical energy have potential and kinetic energy at the same time examle: when you kick a ball. Chemical energy it is cause by chemical reaction example: fossils and batteries. Electrical energy is the energy stored in charge particles within the electric field example: a microphone. Gravitational energy is the motion caused by gravity example: when you jumped up that forces you to come back down.
