Study Notes
Energy Fundamentals
- Energy is the ability or capacity to do work.
- Energy transfer occurs when energy changes from one form to another, such as from electrical energy to light and heat energy.
Energy Transfer Example
- Turning on a lamp is an example of energy transfer, where electrical energy is converted into light and heat energy.
Forms of Energy
- Kinetic energy is the energy of movement, associated with an object's motion.
- Sound energy is a form of energy associated with the vibration of particles, resulting in the perception of sound.
Conservation of Energy Principle
- The conservation of energy principle states that energy cannot be created or destroyed, only converted from one form to another.
