WEP Flashcards
Work
A force as the product of displacement and the component of the force parallel to the displacement
Mechanical Energy
The sum of gravitational potential energy and kinetic energy at a point
Power
The rate at which work is done
Gravitational Potential Energy
The energy an object possesses due to its position relative to the reference point
Kinetic energy
The energy an object has as a result of the object’s motion
Power Efficiency
The ratio of output to input power
Law of Conservation of Energy
The total energy of a system cannot be created or destroyed only transform from one form to another.
Principle of Conservation of mechanical energy
In the absence of air resistance or any other external forces, the mechanical energy of an object is constant.
Work Energy Theorem
The work done by an object is equal to the change in the kinetic energy of the object
Calculate Wnet
Wnet=Change in Ek
