1️⃣ What is Energy?
Energy is the ability to do work or cause change. It exists in different forms:
Mechanical Energy (motion & position)
Thermal Energy (heat)
Electrical Energy (moving electrons)
Light Energy (from the Sun, bulbs)
💡 Example: When you lift a ball, you give it energy. When you drop it, that energy turns into motion!
2️⃣ Gravitational Potential Energy (GPE)
GPE is stored energy an object has due to its height. The higher an object is, the more GPE it has.
🔹 Formula:
GPE=mgh
Where:
m = mass (kg)
g = gravity (9.8 m/s² on Earth)
h = height (m)
3️⃣ Kinetic Energy (KE)
KE is energy of motion. The faster an object moves, the more KE it has.
🔹 Formula:
KE=1/2xmv2
Where:
m = mass (kg)
v = velocity (m/s)
How GPE & KE Work Together 🎢
When you drop an object, GPE turns into KE as it falls!
💡 Example: A roller coaster at the highest point has maximum GPE. As it speeds down, GPE converts to KE, making it move faster!
