Potential energy
In Class 9 Science, students learn that potential energy is the energy stored in an object because of its position, height, or shape. The topic explains gravitational potential energy, the role of mass and height, and the relation E = mgh near Earth’s surface. Students connect the idea with work done in lifting objects, energy transformation, conservation of energy, and the working principle of simple machines in the chapter Work, Energy, and Simple Machines.
