Understanding Work and Energy: Key Concepts and Real-Life Examples
This PowerPoint explains the concept of work and energy in physics. It defines work as the force applied over a distance, emphasizing that only the component of force in the direction of motion does work. The presentation covers examples like pushing a box up a frictionless slope, where gravity performs negative work as the box is raised. Energy is introduced as the ability to do work, with potential energy stored in gravity when lifting objects. The work done by forces like stretching a spring is also explained, where the total work is calculated as the area under the force-distance curve.
