Understanding What Energy Is
Energy is the ability to make things move, change, or work. Everything happening around you—movement, heat, light, and growth—uses energy.
Different Forms of Energy
Energy appears in many forms, including heat, light, electricity, motion, and chemical energy stored in food or fuel. These forms can change from one to another.
How Energy Works
Energy cannot be created or destroyed. It can only change form. For example, the energy in food becomes movement, and electrical energy becomes light from a lamp.
Where Energy Comes From
Energy can come from the sun, food, batteries, fuel, wind, or stored forces like gravity. Nature constantly transfers energy between objects and systems.
Why Energy Matters
Energy powers homes, machines, bodies, and ecosystems. Without it, nothing could move, grow, heat up, cool down, or function.
The Simple Takeaway
Energy is what makes things happen. It exists in many forms and constantly changes from one type to another to keep the world moving.
