A feather of mass 0.001 kg falls from a height of 2 m under realistic conditions it experiences air resistance based on what you know about friction what can you say about the kinetic energy of the feather as it reaches the ground

The position vector of a particle of mass 2 kg is given as a function of time by ~r = (6 m) ˆı + (3 m/s) t ˆ. Determine the magnitude of the angular momentum of the particle with respect to the origin at time 3 s.

No force is necessary to

Productivity can best be described as

Why is the work output of any real machine less than the work needed to operate it? work is gained due to friction work is lost due to friction friction reduces the work input
