Kinetic energy and potential energy are two important types of energy in physics.
Kinetic Energy:
- Kinetic energy is the energy of things that are moving.
- For example, a car going 60 km/h has kinetic energy because it is in motion.
- The formula for kinetic energy looks like this:
KE=21mv2
In this formula, m stands for mass (how heavy something is) and v stands for velocity (how fast it’s going).
Potential Energy:
- Potential energy is the energy that is stored based on where something is located. It has the ability to do work.
- For example, think about a rock at the edge of a cliff. It has gravitational potential energy because it could fall.
- The higher the rock, the more potential energy it has. It is calculated by this formula:
PE=mgh
Here, m is mass, g is gravitational acceleration (how gravity pulls objects), and h is height (how high it is).
In short, kinetic energy is all about movement, while potential energy is all about position!
