... – The CM is not an inertial reference frame! Is this OK?? (After all, we can only use F = ma in an inertial reference frame). • YES! We can always write t = I for an axis through the CM. – This is true even if the CM is accelerating. – We will prove this when we discuss angular momentum! ...

... ordinary function. A potential energy function that takes on more than one value is not of much use to us. (One is reminded of a painting by M.C. Escher in which he manages to distort reality enough so that a staircase appears always to be descending!) Under what conditions will it be possible to fi ...

... • If the reaction force, R, is larger than your weight, you feel heavier and the net force acts upward, resulting in an upward acceleration (e.g. speeding up in the upward direction) • If the reaction force, R, is equal to your weight, you feel neither heavier nor lighter, and the net force is zero, ...

Work and Energy
... Power is defined as the rate at which energy is transferred or transformed. Energy transfer into the system is done by external work, so power is often defined as the rate that work is done. P = W/t ...
