S8P5.a - S8P5.c

TermDefinition
S8P5.a Recognize that every object exerts gravitational force on every other object
Law of Universal Gravitation states that the force of gravity acts between all objects in the universe
Mass a measure of the amount of matter in an object
Sir Isaac Newton's First Law of Motion states that an object at rest will stay at rest and an object in motion will stay in motion unless an unbalanced force acts on the object
S8P5.b demonstrates the advantages and disadvantages of Series and Parallel Circuits
Electric Current the rate at which charges pass through a given point; measured in amperes
Potential Difference the difference in Potential Energy between two locations
Voltage the Potential Difference between two points; measured in volts
Insulator a material that does not conduct heat of electrical energy well; often used to prevent energy from leaving a particular area
Circuit a closed path through which electricity can flow
Load a device in a Circuit that does work using electrical energy
Conductor a material that allows heat or electrical energy to flow through it easily
Resistor an object added to a Circuit that resists the flow of electrical energy; inhibits the flow of an electric current by producing a voltage drop when the current passes through it
Switch a device used to control the flow of current through a Circuit
Series Circuit a Circuit in which the parts are joined one after another such that the current in each part is the same
Parallel Circuit a Circuit in which the parts are joined in branches such that the current in each part is the same
S8P5.c Investigate/explain that electric currents and magnets exert force on one another
Magnetic Force the force of attraction of repulsion generated by moving or spinning electric charges
Magnetic Field an area surrounding a magnet in which the Magnetic Force exists
Electromagnetism the interaction between electricity and magnetism
Electromagnet a coil that has a soft iron core that acts as a magnet when an electric current is in the magnet
Electric Motor a device that converts electrical energy into mechanical energy
Generator a device that transforms mechanical energy into electrical energy
