Study Notes
Kinetic Energy
- Defined as the energy possessed by an object due to its motion.
- Calculated as ( KE = \frac{1}{2}mv^2 ), where m is mass and v is velocity.
Conduction
- A method of heat transfer through direct contact between materials.
- Occurs primarily in solids but can also happen in liquids and gases.
Potential Energy
- Energy associated with the position or condition of an object.
- Commonly defined as ( PE = mgh ), where m is mass, g is gravitational acceleration, and h is height.
Convection
- Energy associated with the movement of heat within a liquid or gas.
- Involves the transfer of warmer, less dense areas of fluid rising while cooler, denser areas sink.
Insulator Characteristics
- Materials that resist the flow of heat.
- Often provide thermal resistance, minimizing energy loss.
Energy and Change in Matter
- Energy associated with the ability to cause change in matter is known as chemical or potential energy.
- Capable of initiating reactions, leading to transformations in physical or chemical states.
Conductor Characteristics
- Materials that allow heat to flow easily through them.
- Typically characterized by high thermal conductivity, enabling efficient heat transfer.
Chemical Energy
- Energy released during chemical changes or reactions.
- Stored in the bonds of chemical compounds, released when those bonds are broken.
