10.4 Newton`s Third Law of Motion and Momentum
... • Momentum is a measurable vector quantity (product of mass and velocity) • Inertia is dependent on mass, but it is an object’s resistance to a change in velocity What has more momentum: a 200 pound man running at 1 mph or a 65 pound girl running at 4 mph? Why? ...

... due to kinetic friction. Angular momentum about the center of mass is not constant because the friction exerts a torque about the center of mass. Angular momentum about a fixed point on the ground is constant because the sum of the torques about that point is zero. The friction force will always be ...

... The idea is to use the vertical density distribution (z) and vertical velocity distribution f(W) of a tracer sample of stars to derive dynamically the total (luminous + dark) density and surface density of the disk, e.g. via Jeans equation. Is there more matter in the disk that we can account for f ...

... Impulse is not a property of the object, but something that it can give or get from an interaction. Notice that it is not motion that gives us an impulse (v) but a change in motion (Dv). ...

... Crab Nebula flashes at a rate of 30 times/s. Suppose the light pulses are caused by the rotation of a spherical object that emits light from a pair of diametrically opposed “flashlights” on its equator. What is the maximum radius of the pulsar if no part of its surface can move faster than the speed ...
