In its simplest form, energy is the ability to do work. It comes in many different forms, including electromagnetic radiation, sound waves, chemical energy, and nuclear energy. All of these forms of energy have one thing in common: they can be converted into other forms of energy.
For example, when a light bulb is turned on, the electrical energy is converted into light and heat. The light waves travel through the air and eventually hit your eyes, which converts the light into electrical impulses that your brain can interpret as sight. The heat energy from the bulb warms up the air around it.
In the world of physics, energy is a bit more complicated than that. It’s actually a physical quantity that can be measured. And it turns out that there are two different types of energy: potential energy and kinetic energy.
Potential energy is stored energy. It’s the energy that an object has because of its position. For example, a rock at the top of a hill has potential energy because it could roll down the hill. The higher the rock is, the more potential energy it has.
Kinetic energy is energy that’s in motion. It’s the energy that an object has because it’s moving. For example, a ball rolling down a hill has kinetic energy. The faster the ball is moving, the more kinetic energy it has.
In the real world, energy is never just potential or kinetic. It’s always a combination of the two. For example, a roller coaster at the top of a hill has both potential and kinetic energy. The potential energy comes from the height of the hill, and the kinetic energy comes from the motion of the roller coaster.

Q: What does it mean to be pure energy?
A: In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but which is always conserved. In other words, energy can neither be created nor destroyed. It is often said that energy is the ability to do work.
Q: Is a photon pure energy?
A: Yes, a photon is considered to be a “pure” form of energy.
Q: Why is light considered pure energy?
A: Light is considered pure energy because it is a form of energy that is not contaminated by any other form of energy.
