Work, Energy, Power, and Machines
... A motor is attached to one of the pulleys so that as it turns, the belt causes the second pulley to turn. To have the least effort force, the effort distance must be the greatest. In this case the effort distance is the number of turns around – the ROTATIONS! Which pulley will have to go around more ...

... This is exactly the same as the “critical velocity” for the roller coaster car to stay on the track at the top of the loop-the-loop! (slide 35) In fact, in both cases the object is in “freefall” and feels “weightless”. The expression for vorb is valid for “low orbits”, i.e., r ~ radius of the earth. ...

... The gravitational force is exactly (i.e., as precisely as we can measure it!) proportional to the inertial mass. Therefore the acceleration due to gravity is independent of the mass of the accelerating object. For example, at the surface of the Earth, all falling objects have the same acceleration d ...

... Two cars are initially at rest. Car A is at x = 0, and car B is at x = + 600 m. They start to move, at the same time, along the same line in the positive x direction with constant accelerations: a A = 4.00 m/s2 and a B = 1.00 m/s2. How long does it take car A to overtake car B? A) B) C) D) E) ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
