Units of Energy: Define common units used to measure energy, such as joules, calories, and kilowatt-hours.
Energy: Units of Measurement
Picture this: You’re trying to measure the energy in your morning coffee, but you don’t know how! Don’t worry, my friend, we’ve got you covered.
Just like we have different units to measure distance (kilometers, miles) and weight (kilograms, pounds), we have units of energy too. The most common one is the joule (J). It’s named after James Joule, a scientist who made major discoveries in energy.
The joule is a tiny unit, so we often use larger ones like the calorie (cal) or the kilowatt-hour (kWh).
One calorie is the amount of energy needed to raise the temperature of one gram of water by one degree Celsius. It’s also the energy you get from a small gummy bear (yum!).
A kilowatt-hour is a more substantial unit. It’s the amount of energy used by a 1,000-watt appliance running for one hour. Think of it as the energy your fridge needs to keep your veggies crisp for a night.
So, there you have it, the units we use to measure energy. Now you can confidently describe the punch in your coffee or the power of your favorite electronic devices using the correct energy units!
