Study Notes
Energy Concepts
- Energy is defined as the ability to do work or cause change.
- Work occurs when a force acts on an object causing it to move.
Types of Energy
- Kinetic Energy: Energy possessed by an object due to its motion.
- Potential Energy: Energy that is stored based on the position or shape of an object.
Forms of Potential Energy
- Gravitational Potential Energy: Depends on the height of an object above the ground.
- Elastic Potential Energy: Energy stored in objects capable of being stretched or compressed.
Fundamental Concepts
- Mass: Measure of the amount of matter in an object.
- Matter: Anything that has mass and occupies space, composed of atoms.
- Velocity: Measurement of speed in a specific direction.
Units of Measurement
- Joule: The standard unit for measuring work or energy.
Mechanical Energy
- Comprises both kinetic and potential energy associated with the motion or position of an object.
Thermal and Electrical Energy
- Thermal Energy: The total internal energy (potential and kinetic) of particles in a substance.
- Electrical Energy: Energy resulting from the movement of electric charges.
Chemical and Nuclear Energy
- Chemical Energy: Potential energy stored within chemical bonds of molecules.
- Nuclear Energy: Potential energy held in the nucleus of an atom, the smallest unit of matter.
Electromagnetic Energy
- Energy related to light and other forms of radiation.
Conservation of Energy
- The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.
