... It always bothered me that if the same impulsive force were applied on the bar between the two masses, i.e. at the CM, the barbell would move at the SAME speed we just calculated for the CM, but without rotation. From energy considerations, it seems that applying the same force in two locations impa ...

... The “F” in the above equations is ALWAYS the NET force. Maybe, think of NET force as the “extra” force applied beyond the amount needed to balance all forces. If there is no “extra” force, there will be no acceleration and the object will either remain at rest or continue straight-line motion at a c ...

... We all know the answer, that is until we become physicists! Then we get into problems. A point particle will move from rest or change its velocity only if there is a net external force on it; and it changes its energy only if the external force does work on it. For a system of particles, the first p ...
