Study Notes

Kinetic Energy

Defined as the energy an object possesses due to its motion.

Potential Energy

Energy held by an object based on its position or condition, often referred to as stored energy.
Gravitational Potential Energy: Energy stored related to an object's height, found in examples like:
- Sheikrah ride
- Rock perched on a cliff
Elastic Potential Energy: Energy stored in elastic objects due to deformation, seen in:
- A bow prepped to shoot
- Stretched exercise bands
Chemical Potential Energy: Energy stored in atomic or molecular bonds, found in:
- Batteries
- Coal, oil, and propane

Sound Energy

Energy produced from vibrating molecules that can be heard, exemplified by:
- Sirens
- Tubas

Chemical Energy

Energy derived from the combustion or digestion of molecules, found in:
- Food
- Wood
- Gasoline

Radiant Energy

Energy presented in the form of:
- Solar Energy: Sunlight
- Light Energy: Emitted from light bulbs or fire
- Heat/Thermal Energy: Like the energy in boiling water

Electrical Energy

Energy resulting from the flow of electrical charges through a conductor, evident in:
- Electricity powering devices
- Turning on a radio
- Lightning strikes

Atomic/Nuclear Energy

Energy originating from nuclear reactions, either from splitting atoms in power plants or fusion in the sun, illustrated by:
- The sun's energy
- Atomic bombs

Mechanical/Motion Energy

Energy generated by muscle movements and actions, examples include:
- Clapping hands
- Wind energy

Law of Conservation of Energy

States that energy cannot be created or destroyed but can transform between different forms.

Energy Transfer

The process of moving energy from one form to another, involving various energy types such as:
- Sound
- Chemical
- Radiant
- Electrical
- Atomic/Nuclear
- Mechanical/Motion

Heat Transfer

Defined as the movement of heat from warmer objects to cooler ones, with mechanisms of transfer including:
- Radiation: Transfer through empty space, e.g., sun warming the Earth or fire warming a person without contact.
- Conduction: Direct transfer through contact among molecules, as seen in:
  - A pan heating water via physical contact
  - Holding an ice cube that warms due to hand heat
- Convection: Heat transfer in liquids and gases, utilizing convection currents where heated molecules rise, illustrated by:
  - Hot air balloons rising
  - Balloon inflating with hot gas
