Science Proficiency 7

Key terms to know to be successful on your science proficiencies.

AB
AccelerationIs the rate of change of velocity as a function of time.,
Balanced ForcesIs when two equal forces are applied on an object pushing both ways,
ConductorA material which permits a flow of energy,
Consumption (Energy)The use of energy as a source of heat or power or as a raw material input to a manufacturing process.,
CurrentThe time rate of flow of electric charge, in the direction that a positive moving charge would take and having magnitude equal to the quantity of charge per unit time: measured in amperes.,
Electric ForceThe force exerted by stationary objects bearing electric charge on other stationary objects bearing electric charge.,
ElectricityA physical phenomenon associated with stationary or moving electrons and protons,
Generating SourcesA device that produces electrical energy from a mechanical energy source,
InsulatorIs a material that resists the flow of electric charge,
Kinetic EnergyIs the energy of motion, observable as the movement of an object, particle or set of particle.,
Laws of MotionOne of three basic laws of classical mechanics,
Magnetic PoleEither of two regions in a magnet where the magnetic induction is concentrated.,
MatterSomething that occupies space and can be perceived by one or more senses; a physical body, a physical substance, or the universe as a whole.,
Mechanical EnergyA combination of kinetic and potential energy resulting from the force of gravity or the movement or release of a machine component, such as a spring, clamp, or wheel.,
MotionIs one that is not opposed by an equal and opposite force operating directly against the force,
Potential EnergyThe ability of a system to do work due to its position or internal structure.,
Transfer (Energy)Energy can be transferred from one object to another by doing work. When work is done on an object, it results in a change in the object's motion (more specifically, a change in the object's kinetic energy).,
Unbalanced ForcesOpposing forces that are pushing or pulling against each other an equal amount,
VelocityIs the rate of change of velocity over time.,
