Work
Occurs any time a force acts to move an object.
What is work?
What is a simple machine?
The ability to do work
What is energy?
The measure of hotness or coldness of a substance, which is proportional to the average kinetic energy of its particles.
What is temperature?
The category for liquids, gases, and plasmas.
What are fluids?
Equal to work divided by time
What is power?
A wheel and axle system with a groove around the perimeter of the wheel for a rope used in moving heavy objects.
What is a pulley?
The law of conservation of energy.
Any property that predictably changes with temperature.
What is a thermometric property?
A measurement of the amount of force acting upon a given area.
What is pressure?
Equal to force times distance
What is work?
A rigid bar that turns on a pivot point
What is a lever?
Two general categories that all types of energy fall under.
What is kinetic or potential energy?
The sum of the kinetic energy of all a substance's particles.
What is kinetic energy?
A measurement of a fluid's resistance to flowing.
What is viscosity?
The measure of the change in input needed to do a certain amount of work.
What is mechanical advantage?
Two planes connected with an acute angle that is thick at one end and thinner at the other.
What is a wedge?
The sum of any kinetic energy and all the forms of potential energy in a system.
What is mechanical energy?
A material through which energy flows easily.
What is a thermal conductor?
The volume of a sample of gas at constant pressure is directly proportional to its temperature.
