2. Potential Energy – The Energy of Position

3. What is Potential Energy? Definition: Potential energy is the energy stored in an object due to its position or state. Unlike kinetic energy, which is energy of motion, potential energy is stored and can be released The unit for energy in the International System of Units (SI) is the J oule (symbol J). Example: A stretched rubber band has potential energy. When released, it converts into kinetic energy.

4. Types of Potential Energy There are several types of potential energy, but the most common are: Gravitational Potential Energy Energy stored in an object due to its height above the ground. The higher and heavier an object, the more GPE it has. Elastic Potential Energy Stored energy in objects that can be stretched or compressed (rubber bands, springs ... ). Electric Potential Energy Energy stored in charged particles due to their position in an electric field.

5. Gravitational Potential Energy Ep = m*g*h Where: m = mass (kg) g = gravity (9.8 m/s²) h = height (m) Example: A rock sitting on a cliff has GPE. When it falls, the energy converts into kinetic energy. A roller coaster at the highest point has maximum potential energy, which converts into kinetic energy as it moves down.

6. Elastic Potential Energy Example s : A stretched spring stores potential energy, which is released when you it let go. Trampolines and archery bows also store elastic potential energy. Potential energy in spring : k – stiffness of spring ∆l – elongation of spring

7. Electric Potential Energy It is similar to gravitational potential energy but instead of mass, it depends on electric fields and electric charges . How It Works: Opposite charges (positive and negative) attract each other. If you separate them, you store potential energy in the system. Real-Life Example: Batteries: Inside a battery, chemical reactions separate positive and negative charges, creating electric potential energy. When you connect a circuit, this energy is released as electrical energy.
