Chapter 2 - Work and Energy Flashcards
Energy
Refers to a system’s ability to do work
Kinetic Energy
Energy of motion
Potential Energy
Energy that is associated with a given object’s position in space or other intrinsic qualities of the system
Elasticity
When a spring is stretched or compressed from its equilibrium length
Total Mechanical Energy
Sum of an object’s potential and kinetic energies
Conservative Forces
Path independent and do not dissipate energy
Work
Process by which energy is transferred from one system to another
P-V Graphs
Graphical form of gas expansion and compression processes with volume on x-axis and pressure on y-axis
Power
Refers to the rate at which energy is transferred from one system to another
Work-Energy Theorem
Direct relationship between the work done by all the forces acting on an object and the change in kinetic energy of that object
Mechanical Advantage
Measure of the increase in force accomplished by using a tool
Simple Machines
Inclined plane, wedge, wheel and axle, lever, pulley, screw
