Relationship Between Energy and Work - JSS2 Basic technology Lesson Note

Work: Work is done when a force is applied to an object, causing it to move. The formula for work is ( W = F × d ), where ( W ) is work, ( F ) is the force applied, ( d ) is the distance.

Energy and Work: Work and energy are closely related concepts. When work is done on an object, energy is transferred to or from the object. For example, lifting a weight involves doing work against gravity, transferring energy to the weight as gravitational potential energy. Similarly, when a car accelerates, work is done by the engine, converting chemical energy in the fuel into kinetic energy of the car.
