PHYSICS 214 TEST 1 12 February 2008
... This is a closed book exam, but a crib sheet is provided and you can use your own crib sheet. You may also use a calculator. Any form of cheating will result in severe penalties, which will include a score of zero for this exam and may result in a grade of F for the course and referral to the Dean o ...

Roller Coaster - Pennsylvania State University
... At the same height, a roller coaster has the same velocity wherever its position is. However, it is not that simple thing to think about its velocity at certain points only based on the knowledge of potential and kinetic energy. The reason is that there are also friction, brake, and acceleration to ...

LECTURE 27: Gravitational potential energy
... As seen in the practice problem above, the work from the force of gravity is the same regardless of which path the object traversed. We can generalize further and claim that no matter what path, no matter how silly it may be, the work from the force of gravity on an object is independent of the path ...
