Why Do We Need To Know About Lever
Learning about levers helps us understand how simple machines make work easier. Levers allow us to lift heavy things using less effort by pushing or pulling over a longer distance, similar to how a seesaw works. This idea is used in building things and in gardening.
People who work in moving companies, design houses, or build structures often use levers to lift and move big objects more easily. Knowing how levers work teaches us useful ways to handle everyday tasks. Moving the middle part of a lever close to the object you want to lift makes it easier. This shows us how important levers are, not just in our daily lives but also in many jobs.
