Study Notes
Types of Energy
- Energy is the ability to do work or cause change. It comes in many forms.
- We use energy every day to do things like move, light up our homes, and cook food.
- Different types of energy are created and used in various ways.
Different Forms of Energy
- Mechanical Energy: This is the energy of motion. Examples include:
- A bouncing ball.
- A moving car.
- Your arm as you swing it.
- Thermal Energy: This is the energy of heat. Examples include:
- The heat from a fire.
- The warmth of the sun.
- The hot water in a bath.
- Light Energy: This energy is what allows us to see. Examples include:
- Sunlight.
- A lamp shining.
- A fire producing light.
- Sound Energy: Energy from vibrating objects. Examples include:
- A bell ringing.
- Music from a speaker.
- Your voice.
- Electrical Energy: The energy that makes electronics and appliances work. Examples include:
- A light bulb.
- A computer.
- A television.
- Chemical Energy: Stored energy found in food and fuel. Examples include:
- Food you eat (provides energy for your body)
- Batteries
- Fuels like gasoline or wood
Sources of Energy
- Renewable Energy: These resources can be replenished naturally. Examples include:
- Solar Energy: From the sun.
- Wind Energy: From the wind's movement.
- Hydropower: From the movement of water, like rivers.
- Biomass: From plant materials.
- Non-Renewable Energy: These resources cannot be replaced quickly. Examples include:
- Fossil Fuels: Coal, oil, and natural gas. These sources were formed from ancient plants and animals over millions of years.
Transforming Energy
- Energy can change from one form to another.
- A light bulb, for example, changes electrical energy into light energy and heat energy.
- A car engine changes chemical energy (from the fuel) into mechanical energy (moving the car).
- Plants use sunlight (light energy) to produce food through photosynthesis and store energy as chemical energy.
Conservation of Energy
- Energy cannot be created or destroyed, only changed from one form to another.
- We need to use energy wisely, to keep our environment healthy.
- This is called energy conservation.
