Science Flashcards
The ability to do work or cause change
Energy
Unit of Energy
J- Joules
Energy due to objects motion or position; the total potential and kinetic energy
Mechanical Energy
The vibrations of the electric charge or magnetic field
Light Energy
Energy caused by the movement of flow of electrons
Electrical Energy
The energy stored in bonds between the atoms in a compound
Chemical Energy
Energy created by the motion of atoms and molecules that occur within a substance
Thermal Energy
Related to the potential energy stored in bonds between particles in the nucleus of an atom
Nuclear Energy
Energy in the vibration of particles of an object
Sound Energy
- Energy due to an objects motion, position, or shape of an object
- Usually used to describe a large object
- The sum of kinetic and potential energy
Mechanical Energy
- Energy that isn’t due to an objects motion, position, or shape of an object
- Usually used to describe an object at its atomic level
- Ex. Electrical, Nuclear, Thermal, and Sound
Non-Mechanical Energy
When an object moves a distance when a force is applied parallel to the motion
Work
More Force > More Work > More energy being transferred
Relationship between work, force, and energy
Motion in the same direction as the force
Positive Work
Motion in the opposite direction of the force
Negative Work
