Flashcards
Example of Potential Energy
Example of Potential Energy
Potential energy is stored energy, waiting to be used to do work.
Kinetic Energy Formula
Kinetic Energy Formula
Kinetic energy is energy of motion. KE = 1/2 * mass * velocity^2
Renewable Energy Example
Renewable Energy Example
Renewable energy comes from naturally replenishing resources.
Study Notes
Energy Types
- An example of potential energy is an object at rest, such as a ball at the top of a hill, which has stored energy due to its position.
Kinetic Energy
- The formula for calculating kinetic energy is KE = 0.5mv^2, where m is the mass of the object and v is its velocity.
Renewable Energy
- An example of renewable energy is energy generated from natural resources that can be replenished over time, such as solar energy, wind energy, or hydro energy.
