Question 2

What's the difference between energy and power?

Accepted Answer

Energy is the total amount of work or heat (measured in joules, calories, or kilowatt-hours), while power is the rate at which energy is used or generated (measured in watts). 1 watt = 1 joule per second.

Question 3

Why are there so many energy units?

Accepted Answer

Different fields use different units: physics uses joules, nutrition uses calories, electricity uses kilowatt-hours, and heating/cooling uses BTUs. Each unit evolved for specific practical applications in their respective fields.

Question 4

What is a kilowatt-hour (kWh)?

Accepted Answer

A kilowatt-hour is the energy used by a 1,000-watt appliance running for one hour. It's commonly used for electricity billing. 1 kWh = 3,600,000 joules = 3.412 BTU.

Question 5

How do food calories relate to scientific calories?

Accepted Answer

Food Calories (with capital C, also called kilocalories) are 1,000 times larger than scientific calories (lowercase c). 1 Calorie = 1 kcal = 4,184 joules. Food labels show Calories (kcal).
