S8P5.a - S8P5.c
Term | Definition |
---|---|
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 |
