Energy
In Class 9 Science, this topic introduces energy as the capacity to do work and connects it with everyday events and mechanical systems. Students learn the units of energy, the difference between kinetic and potential energy, and how energy changes from one form to another. They explore the law of conservation of energy, understand the relationship between work and energy, and relate these ideas to the working of simple machines and practical situations.
