Angular Position Control
... The process consists of a DC motor, a reduction unit, a potentiometer and a visualization system. The DC motor (A) generates the actuating signal for the position control system and the reducer (B) reduces the angular rotation velocity. The reducer draft drives the pointer on the graduated scale of ...

... fall back on the immense distance, which they say will not permit the motion arising in the fixed stars from the force of gravity to be perceived by the senses, even after an immense number of ages [Newton’s implicit assumption]. [Boscovich’s argument, concession] In this they assert nothing but the ...

... A cart with a mass of 102 kg is pushed up a ramp. The top of the ramp is 4 meters higher than the bottom. How much potential energy is gained by the cart? If an average student can do 50 joules of work each second, how much time does it take to get up the ramp? ...

... The total force is just the force per ion times the number of ions. We have a density of ions ρN a+ = 3×1020 cm3 , and a volume of V = 120 cm3 . The total number of ions is then just NN a+ = V ρN a+ = 3.6 × 1022 . Note that we don’t really have to convert cm3 to m3 , since the units cancel. Put that ...

1. a) Give the formula for the linear momentum of an object
... b) Formulate the principle of conservation of linear momentum in one sentence. In an isolated system, the total momentum is conserved. c) Repeat this in formula form for the case of masses m1 and m2 colliding with initial velocities v1 , v2 and final velocities v10 , v20 . m1 v1 + m2 v2 = m1 v10 + m ...
