Work, Energy, and Momentum: 12
Work and energy are scalar quantities
-
Work, Energy, and Momentum: 13
Work is equal to the product of the displacement and the component of the force in the direction of the displacement.
-
Work, Energy, and Momentum: 14
For and object traveling in circular motion, the centripetal force never does work.
-
Work, Energy, and Momentum: 15
Mechanical energy is the sum of all kinetic and potential energies.
-
Work, Energy, and Momentum: 16
Work-Energy Theorem: the net work is equal to the change in kinetic energy.
-
Work, Energy, and Momentum: 17
Conservation of mechanical energy under the action of a dissipative force includes the work due to frictional forces (non-conservation forces)
-
Work, Energy, and Momentum: 18
Power is the time rate of change of work or energy, but it can also be calculated using forces x speed.
