... energy may seem to be lost in the impact. However, the energy lost merely changes from kinetic or potential energy to another form such as sound, heat or light. The net energy in any system is always conserved. For most applications, assuming no energy is lost is accurate enough to solve the problem ...

... 31. The acceleration of an object acted upon by a force is directly proportional to the applied force and inversely proportional to the mass. 32. Based on Newton’s 2nd law, if mass of an object doubles, for the same applied force, what happens to its acceleration? 33. For the same mass if the force ...
