Lesson 40: Conservation of Energy Total Mechanical Energy We sometimes call the total energy of an object (potential and kinetic) the total mechanical energy of an object. “Mechanical” energy doesn’t mean that it always has to involve machines. An apple falling off a cliff has gravitational potential and kinetic energy, so it therefore has mechanical energy. Em = Ek + Ep Example 1: A 14
Determine the work done on the block by b) the pushing force, c) the force of gravity, d) the normal force, e) all of the forces (the net force) on the block. f) Find the change in the kinetic energy …
Usually work-energy is simpler to use, but it’s not always possible to use it. Being able to identify which problems make good candidates for work-energy is an valuable skill to have. As illustrated in the video below, here are some good rules of thumb.

D) The kinetic energy of the object is multiplied by 8 E) The momentum and the kinetic energy of the object are quadrupled Two object A and B of velocities v1 and v2 have momenta with equal magnitude.
Kinetic energy (KE) is the energy of motion, which may be a horizontal, vertical, or spinning motion. To To calculate the KE of a moving object, use the following formula:
The workdone by a conservative force is equal to the negative of the potential energy.When the wokdone is positive ,the potential energy decreases. The rate of change of total momentum of a many -particle system is proportional to the net force external to the system ;the internal forces between particles cannot change the momentum of the system.The workdone by the conservative system is …
