Mechanical Energy. Work is a force acting upon an object to cause a displacement. In all instances in which work is done, there is an object which supplies the force in order to do the work. ... This new equation for power reveals that a powerful machine is both strong (big force) and fast (big velocity). ...

Rearrange equation (1) so all terms in m1 are on one side of the equation and m2 on the other: 1/2m1(v1)2 - 1/2m1(v1’)2 = 1/2m2(v2’)2 - 1/2m2(v2)2 . ... The kinetic energy lost by M1 is transferred to M2. If, on the other hand, the spring had been inelastic (say a coil of soft solder) it would not have returned the energy after compression ...

Aug 05, 2013 · We can now add the potential energy of a spring to the conservation of mechanical energy equation: This equation deals with changes in energy for: kinetic energy, gravitational potential energy, and potential energy of a spring. We can now use this to solve the odd problem or two. This is called, “applying the theory.”

Mechanical Energy is conserved since no thermal energy is produced. at 1 m ME = PE + KE. ME = mgh + KE. 1176 J = (30kg)(9.8 m/s2)(1 m) + KE. 1176 J = 294 J + KE. 882 J = KE. Conservation of Energy Table for Question 20 (Notice Mechanical energy is conserved.)

Internal energy and heat are thermal energy forms that cannot be converted directly into useful work. For systems that involve significant temperature changes, the mechanical energy terms are usually negligible compared with the thermal terms. In such cases the energy balance equation reduces to a “heat or enthalpy balance”, i.e. dh = (q.
