Mechanical energy Flashcards
Work done on an object
The product of the displacement and the component of the force parallel to the displacement.
Gravitational Energy
The energy an object possesses due to its position relative to a reference point
Kinetic Energy
The energy an object has as a result of the object’s motion
Mechanical Energy
The sum of gravitational potential and kinetic energy at a point
Law of conservation of energy
The total energy in a system connot be created nor destroyed; only transferred from one to another
Work-energy theorem
The work done by a net force on an object is equal to the change in the kinetic energy of the object
Power
The rate at which work is done or the rate at which energy is transferred
One watt
The power when one joule of work is done in one second
