... Again by superposition, U = U1 + U2 + U3 + U4. Since all the masses are the same, the only difference between the Ui’s is the distance from the mass Mi to the test mass m. For the two righthand masses, r1 = a/2. For the two left-hand masses, r22 = (a/2)2 + a2 = 5a2/4, and so r2 = 5a/2. U = –2 G M m ...

... The figure shows a variation of Barton’s pendulum. A, B and C are three paper cone pendulums of different lengths suspended from the string. The heavy bob is pulled well aside and released so that it oscillates on a plane perpendicular to the paper. The paper cone pendulums are forced into oscillati ...

... When two or more particles are connected together we usually model each particle separately and use simultaneous equation to solve. EXAMPLE A car of mass 1 tonne tows a trailer of mass 400 kg along a road with a constant acceleration of 2 ms-2. If the tractive force due to the car’s engine is 4000 N ...
