PHYSICS 231 Review problems for midterm 1 1 PHY 231
... Initially, the velocity is pointing up, but is decreasing in magnitude (speed is decreasing) since the gravitational force is slowing it down. This goes on until it reaches the highest point, where the velocity/speed equals zero. The ball than moves down: the velocity becomes negative, but the spee ...

... In order for the damping ratio δ to be less than zero, that is, to be negative, we would have to have the opposite of damping, something that puts energy into the system instead of taking it out. As the energy is added to the system the amplitude grows and grows. The energy is added by an outside so ...

... (b) The riders in the Gravitron carnival ride (Section 6.4) have a centripetal acceleration caused by the normal force of the walls on them. Another example would be the biological sample in a centrifuge. The test tube walls exert a normal force on the sample toward the center of the circle. Assess: ...
