WORK, ENERGY AND POWER (PART 1)
Work is the transfer of energy when a force is applied to an object, causing it to move in the direction of the force, calculated as force × distance × cos(θ). Energy is the capacity to do work and comes in forms like kinetic energy (motion), potential energy (stored), and thermal energy. Power is the rate at which work is done or energy is transferred, calculated as work ÷ time and measured in watts. These concepts explain the interaction and transformation of forces and energy in physical systems.
