I’m just gonna say that in the next few lectures you’ll notice a common theme: that I’m going to keep saying, “this is just like we did before, only now for rotational motion.” Previously we saw that kinematics equations have rotational equivalents, and here we are seeing that you need a torque to c ...

... Assume that there is a constant frictional torque about the axis of the rotor. The object is released and falls. As the mass falls, the rotor undergoes an angular acceleration of magnitude 1. After the string detaches from the rotor, the rotor coasts to a stop with an angular acceleration of magnit ...

... When you strike a wall, does it hurt your hand? You might say the wall struck you. Newton would say the force you applied to the wall was the same as that which the wall applied to you. The wall is bigger and more massive, therefore has more inertia and was not harmed as much as you. If you push on ...
