The Skate Park – Intro to Energy and Work PhET Lab Name:
... When Tony Hawk (super skater) wants to launch himself as high as possible off the half-pipe, how does he achieve this? The skate park is an excellent example of the conservation of energy. The law of conservation of energy tells us that we can never create or destroy energy, but we can change its fo ...

... When a person’s combined work and heat output is greater than the energy consumed they loose weight. The energy input of living organisms is in the form of food. Food is then broken down by the body: some of it is used right away and some of it is stored. If the stored energy is not used, it stays i ...

Section 4: Conservation of (Mechanical) Energy
... This is called the ``work-energy theorem''. In words this says that the change in kinetic energy is equal to the work done by the force on mass . So this kinetic energy is a pretty neat thing. If you know its change, you can figure out how much work was done by all the forces acting on the particle. ...

... • Analysis can be done at Quasi-equilibrium, which is to say the system is changing in increments at which analysis can be done. If the time change at which the analysis is done is small enough, the system can be assumed to be in Quasi-equilibrium. • ALSO • For open systems (e.g. control volumes) th ...

... -The sum of the Potential and Kinetic Energy of a system. Emec = K + U -For an isolated system, the mechanical energy of the system is conserved. U1 + K1 = U2 + K2. -From this we can see that: ∆Emec= 0 = ∆K + ∆U W= ∆Emec. This is work done on a system by an external force. (friction involved) W= ∆Em ...
