... 7. Momentum conservation often assumes that the mass of an object remains constant throughout a process or event. However, a change in momentum can also occur when mass changes. Consider an automobile with a full tank of gasoline traveling at a velocity of 24.44 m/s to the east. The mass of the car ...

PHYSICS 151 – Notes for Online Lecture #16
... I mentioned earlier that the gravitational potential energy is path independent – that is, it depends only on the starting and ending points of the motion and not on how you get there. The forces for which the amount of work depends only on the starting and ending points are called conservative forc ...
