Term Definition
battery it stores chemical energy and turns it into electrical energy
electrolyte a solution that conducts electricity
porous barrier it is a barrier between the two metals so the electrons don't mix
chemical energy a form of potenial energy it is stored in a battery
mechanical energy energy in the form of parts moving in a machine
potential energy stored energy the amount of potential energy of an object depends on its position or condition
stored energy energy stored in a battery
gravitational energy potential energy that depends on the hight of an object
electron an elementary particle with negative charge
insulator holds on to electrons tightly does not allow the flow of electricity
conductor holds on to electrons loosely allows the flow of electricity
parallel a set up of batteries that is attached to each other and is not strong but it las long
series a set up that is positive to negative but it does not last long and is very strong
gravity the attraction between two objects
weight the force of gravity on an object
friction the , the resistance encountered when one body is moved in contact with another
work the force on an object over a distance
power the rate of the work being done per second
work formula Work = Force x Distance
power formula Power = Work / Time
Joule the unit for work
newton the unit for force
force a push or a pull
load force the weight of an object
effort force amount of force that is applied to the machine by you
load distance how far the load moves vertically
effort distance the distance you must move to operate a machine
watt the unit for power
simple machine a device for overcoming resistance at one point by applying force at some other point
incline/slope a plane that lifts something gradually to a point
pulley a wheel with a rope or a string the lifts something from point A to B
first class lever the load is being pushed up and the effort is being pushed down, fulcrum in the middle
fulcrum the pivot about which a lever turns
Ideal Mechanical Advantage The mechanical advantage that a machine would have without friction.
