Energy is what helps us do work. There are different types of energy that are important for understanding how work happens. Let's break them down:
Kinetic Energy (KE): This is the energy of things that are moving. We can figure out how much kinetic energy something has with the formula:
[ KE = \frac{1}{2}mv^2 ]
Here, ( m ) stands for how heavy something is, measured in kilograms, and ( v ) stands for how fast it’s moving, measured in meters per second.
Potential Energy (PE): This is the energy that is stored because of an object's position. A common example is when something is high up, like a rock on a hill. We can calculate potential energy using:
[ PE = mgh ]
In this formula, ( h ) is how high something is in meters, and ( g ) is a number that shows how strong gravity is, which is about ( 9.81 , \text{m/s}^2 ).
Mechanical Energy: This is the total amount of energy in a system. It includes both kinetic energy and potential energy.
Thermal Energy: This type of energy is related to heat and temperature. It’s what makes things warm or hot.
Chemical Energy: This energy is stored in the bonds between atoms in molecules. When these bonds break or form during chemical reactions, energy is released.
Electrical Energy: This energy comes from electric charges. It’s very important for making power for our homes and gadgets.
All these types of energy can change from one form to another. This is known as the conservation of energy. It means that energy can’t be created or destroyed, only changed from one form to another.
