Energy is a big part of our daily lives. Knowing how to measure it can help us make smarter choices.
The most common way to measure energy is in joules (J). But what does this really mean for you?
Food Energy: When you eat food, the energy it gives you is measured in joules or calories. For example, one chocolate bar has about 800,000 joules of energy! That's a lot of energy for you to use when you're playing sports or having fun.
Electrical Devices: The energy that electrical devices use is also measured in joules. For instance, if a light bulb uses 60 watts (W), that means it uses 60 joules every second. Knowing this can help you decide on energy-efficient products that save you money and energy.
Understanding energy in joules makes it easier to see how it affects our lives every day!
