Vocab 1
A collection of objects that interact and/or influence one another. These objects often work together to answer a question or solve a problem.
System
The parts (matter or energy) that enter the system from the outside.
System Inputs
The parts (matter or energy) that leave the system.
System Outputs
The separation between a system and its surroundings identifying what is included in the system and what is outside of the system.
System boundary
Electricity
A device that uses mechanical energy and magnets to create electricity.
Generator
The measure of the amount of matter in an object
Mass
Something needed to cause change or do work.
Energy
The energy an object has due to it's motion
Kinetic Energy
The energy an object has due to it's position
Potential Energy
The movement of energy from one object to another, like the pendulum to the box
Transfer of Energy
The rate at which something moves; a form of kinetic energy (also called velocity)
Speed
The change of energy from one to another; like potential to kinetic
Transformation of Energy
Arranged in a straight or nearly straight line
Linear
A device with blades that transforms forward moving kinetic energy into rotational kinetic energy
Turbine
To pull something closer
Attract
The electrical property of a particle that causes it to attract or repel other particles.
Charge
Energy cannot be created nor destroyed, it can only be transformed from one form to another or be transferred from one object to another.
Law of Conservation of Energy
The ability of an object to attract or repel another object using a magnetic force.
Magnetism
To push away
Repel
A temporary magnet made when an electric current flows through a coiled wire.
Electromagnet
The electrical property of a particle that causes the object to exert that can attract or repel other particles.
Static Charge (Static Electricity)
A change that is a result of an action
Effect
The reason why something happens
Cause
The direction an object is facing
Orientation
