When we talk about energy, many students get confused by some common ideas. Here are a few of those misunderstandings:
Energy Isn’t Just Power: A lot of students think energy is only the same as power. But really, power is how quickly energy is used or moved around. You can measure power in watts. Energy, on the other hand, is the ability to do work. For instance, a battery holds energy. The power shows how fast the battery can use that energy.
Energy Can’t Be Made or Destroyed: Some students think that we can create or destroy energy. But that's not true! According to the law of conservation of energy, energy can only change from one form to another. For example, when you are on a roller coaster, at the top, you have potential energy. As you go down, that potential energy changes to kinetic energy, which is the energy of motion. The total amount of energy stays the same.
Not All Energy Is Easy to See: Another common mistake is thinking that energy is only there when we can see it, like with light or movement. However, energy comes in many shapes and forms. There’s thermal energy, which is like heat, and chemical energy, which is found in food or batteries. We can’t always see these types of energy.
Understanding these misunderstandings helps us get a better grip on what energy really means in physics!
