Mechanical energy is the energy of motion and position. It is found in moving objects (like a running car) or stored in stretched or compressed objects (like a stretched rubber band).
Types of Mechanical Energy:
Kinetic Energy (Energy of Motion) 🚗💨
Energy an object has because it’s moving.
Example: A rolling ball or a moving car.
Potential Energy (Stored Energy) 🏔️🔋
Energy stored due to an object’s position or shape.
Example: A stretched rubber band or a lifted weight (it has energy due to gravity).
How is Mechanical Energy Stored?
Pumped Hydro Storage 💧
Water is pumped to a higher place and stored.
When needed, water flows down, spinning turbines to generate electricity.
Flywheel Storage 🔄
A heavy wheel spins very fast to store energy as motion.
When energy is needed, the spinning slows down and converts back into power.
Compressed Air Storage 💨
Air is squeezed into underground tanks under high pressure.
When released, the air expands and turns turbines to create electricity.
Springs & Elastic Storage 🌀
A stretched rubber band or compressed spring holds energy.
When released, it moves quickly (like in a wind-up toy or clock).
Why is Mechanical Energy Storage Important?
✔️ Reusable – It doesn’t waste energy.✔️ Fast Response – Can release energy quickly when needed.✔️ Eco-Friendly – Uses physics, not chemicals.
