Term
Force
Definition
any influence capable of producing a change in the motion of a body. It is a push or pull.
Term
Three ways a force can act on a body
Definition
cause the mody to move, retard or stop a body, and it can change the direction of the body
Term
Resistance
Definition
is any force which can stop or retard the movement of a body. Ex. friction, load, and inertia.
Term
Inertia
Definition
the reluctance of a body to change motion.
Term
Inertia related to
Definition
the quantity of matter in a body. Lead ball vs a wooden ball.
Term
Energy
Definition
a force which can cause a body to move
Term
Forms of energy
Definition
Mechanical, heat, electrical, fluid, light, chemical, and sound
Term
Kinetic energy
Definition
energy in motion
Term
potential energy
Definition
energy of position or store energy
Term
Work
Definition
a force which causes an object to move a distance. This can only be done by kinetic energy. this = Force x distance
Term
Units for work
Definition
foot-pound, joule
Term
Power
Definition
the speed or rate of doing work. This = (force x distance)/time or Work/time
Term
Horsepower
Definition
unit to measure the amount of power produced. 1 of these = 746 watts
Term
Pressure
Definition
the measure of a force's intensity. This = force/area
Term
Mechanical transmission of energy
Definition
is through levers, chains, pulleys, belts, cams, and gears
Term
Electrical transmission of energy
Definition
is through a wire as electricity
Term
pneumatic transmission of energy
Definition
is in the form of compressed air
Term
Hydraulic transmission of energy
Definition
is in the form of pressurized liquid
Term
Heat energy transmission
Definition
is always from higher amounts to lower amounts
