Examples of forms of energy grade 4 science

📚 Quick Study Guide

• 💡 Energy is the ability to do work. It comes in many forms!
• 🔥 Heat Energy (Thermal Energy): The energy of moving or vibrating molecules. Think of a stove or a campfire!
• 💡 Light Energy (Radiant Energy): Energy that travels in waves and can be seen. Examples include sunlight and light bulbs.
• 🔊 Sound Energy: Energy that travels in waves and can be heard. Examples are music and talking.
• ⚡ Electrical Energy: Energy that flows in a circuit. Examples are powering a TV or a light.
• 💪 Mechanical Energy: The energy of motion or position. There are two types: Kinetic (energy of motion) and Potential (stored energy). $E = \frac{1}{2}mv^2$ (Kinetic Energy)
• ⚛️ Chemical Energy: Energy stored in the bonds of atoms and molecules. Examples include food and batteries.
