9-1 Momentum and Its Relation to Force Example 9
... You are designing a conveyor system for a gravel yard. A hopper drops gravel at a rate of 75.0 kg/s onto a conveyor belt that moves at a constant speed v = 2.20 m/s. (a) Determine the additional force (over and above internal friction) needed to keep the conveyor belt moving as gravel falls on it. ( ...

Lesson 2 - Kinetic and Potential Energy - Hitchcock
... • Energy is the ability to cause change. There are different forms of energy. One form is kinetic energy, the energy of motion. • Every moving object has kinetic energy. The faster an object moves, the more kinetic energy it has. If two objects move at the same speed, the object that has more mass w ...

... initially positively charged? Why does the balloon eventually fall? b) Why is it nonsense to think that two electric field lines could cross? c) When a metal object receives a positive charge, does it mass increase or decrease? SOLUTION: a)No, it doesn’t necessarily mean that the wall was initially ...

... 1013 J. To conserve momentum, the alpha particle and proton must move in opposite directions. We’ll apply both conservation of energy and conservation of momentum to find the speeds of the proton and alpha particle. Use conservation of momentum in this process to express the alpha particle’s veloci ...

Rotational Inertia and Angular Momentum
... Because the direction of something rotating is hard to determine, physicists say that the direction of angular momentum is in the plane of the rotation. If this wheel was rotating, we would say its angular momentum is pointed in this direction. So it would want to stay rotating in that direction. ...

... The coincidence of the magnitudes of the two fundamental constants grows curiously stronger. This gives cause to wonder if they are the same phenomenon. This may seem very strange to try to equate one value having the units of coulombs to another value having the units of seconds. However, a coulom ...
