Amusement Park Physics You've studied the motion of a snowboarder in the previous section and analyzed how potential and kinetic
energy changes throughout that motion. Let's mix in a little more fun with our physics.
Imagine a roller coaster ride at an amusement park. As you might guess, a roller coaster is not all thrilling
adventure; there's probably a lot of physics involved too. Based on your analysis of the snowboarder's motion,
answer a few questions about a roller coaster.
Part A
Assuming a nearly frictionless ride, what can you say about a roller coaster's potential and kinetic energy from
the top to the bottom of a hill?

1) sections 1, 2, and 10 are significant primarily because they suggest the likelihood that a) widow wycherly is actually the woman in the full-length portrait. b) dr. heidegger wants to include his guests in an experiment with the water. c) dr. heidegger plans to drink some of the water from the vase and needs witnesses. d) the guests will be asked to witness dr. heidegger's transformation when he drinks the water.

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)

Area around a charged object where the objects can exert a force on another charged objects is an electric
