How force and motion combine to transfer energy through work and power
In short: This video explains the fundamental relationship between force, movement, and energy transfer. You will learn how the direction of a force determines whether work increases or decreases an object's kinetic energy, and how power measures the speed of that process.
The video explores the mechanics of work, defined as energy transferred to or from an object through force. When a net force acts in the same direction as an object's motion, it performs positive work, which increases the object's kinetic energy. Conversely, a force acting in the opposite direction performs negative work, reducing kinetic energy.
Beyond the concept of work, the video introduces power as the rate at which work is performed or energy is transferred over time.
