Unformatted text preview: r force by choosing a specific location as the zero of the function. ∆U = U B − U A ≡ −WA→B U = −Wr →r + U o o Conservation of Mechanical Energy The mechanical energy of an object is defined to be the sum of its kinetic and potential energies. E Mechanical ≡ K + U The work-kinetic energy theorem can be reformulated as a conservation law. Whenever the work done by non-conservative forces is zero, the mechanical energy of that object is conserved. W Non −Conservative Forces = 0 Ÿ ∆E Mechanical = 0 And which takes less >me to get to the boKom? A.  sliding gets there sooner B.  falling gets there sooner C.  they're the same And which takes less >me to get to the boKom?
