While traveling in a train at half the speed of light, you notice time slowing and distances shrinking outside. Your friend on the platform notices your clock ticking slower and the train appearing shorter. Both perspectives, based on relativity, reveal the dramatic effects of traveling at such high speeds, demonstrating time dilation and length contraction, … Read more

The viscosity of a fluid is to be measured by a viscometer constructed of two 5 ft-long concentric cylinders. The inner diameter of the outer cylinder is 6 inches. The gap between the two cylinders is 0.035 inch. and the gap is filled with fluid. The outer cylinder rotates at 250 rpm, and the torque is measured … Read more

(a) Draw a sketch of the situation before the collision and after the collision (label everything).     (b) Total momentum is conserved. See equation lines 8.33 and 8.34 in section 8.4 as a guide. Substitute any known values and simplify the expression as much as possible.  (c) Label this result as Equation #1. (d) … Read more

Physics discussion

Using a real-world example that relates to your major area of study or work experience, find at least two places where potential energy (PE) is added into the system to keep things in motion. Based on your observations, make an estimation of the energy that is being added into the system.
