... What is G in Newton’s Universal Law of Gravity? • G is called Newton’s gravitational constant • G value depends upon the units used for F, the force, M1 and M2 the mass, and d the distance. • If SI, Standard International units, MKS, meterkilogram-second, is used then G=(6.6742±0.0010)×10-11m3s-2kg ...

... The hand is pushing with the same force as before on the new system of blocks. The new system has a larger mass, so the acceleration of the system is smaller than before. Since all the blocks are moving together, the acceleration of block A, which is equal to that of the system, is also smaller than ...

... carrying the 10 kg brick, at a constant speed. How much work did they do? What is the equation for the change in PE of the brick? Change in PE = PE2 – PE1 = (mgh2 – mgh1) But h2 = h1, so no PE is added or change in PE = 0. So no work is done because no potential energy is added to the package. (Agai ...
