Energy
Energy is the capacity of bodies to produce transformations in themselves or other bodies.
Energy Sources
Energy sources are natural resources from which humans can obtain usable energy.
Types of Energy Sources
- Non-renewable: Found in limited quantities and are depleted with use.
- Renewable: Considered inexhaustible as they are continuously renewed.
Energy Principles
- Conservation of Energy: The total energy in the universe remains constant in any process.
- Degradation Principle: With each transformation, energy loses quality and produces new transformations.
Work and Power
Work (W) is done when a constant force (F) is applied to a body, causing a displacement (d) in the same direction as the force: W = F * d.
Power is the rate at which work is done.... Continue reading "Energy, Waves, Sound, Light, and Electricity: Physics Fundamentals" »
