... (b) Now we want to figure out how fast we’d need to rotate it around in order for it to rotate to the top. In this case, it still has the same kinetic energy, for some ω, KE = mR2 ω 2 . Now it has to get to the top, changing its height by R, so p that it’s final potential energy is P E = mgR. Solvin ...

... This is the form of Newton’s law we were looking for. The net external torque τ is directly proportional to the angular acceleration α. This can be applied to any rigid body rotating. The expression mr2 is called the moment of inertia of the particle i. τ = i α Rotational analog of Newton’s second l ...

... A friction force between two objects in contact opposes the sliding of one object over the surface of the adjacent one. It is tangent to the surface of the adjacent object and opposite in direction to the velocity of the moving object. The magnitude of the frictional force is assumed to be proportio ...

... More about rotational inertia: rolling objects down a hill… • Which rolls to the bottom of an incline first, a solid ball, a solid cylinder or a ring? First ask: which has smallest rotational inertia? – since this will resist rolling the least, so will reach the bottom first. The shape which has mo ...
