The electric potential energy of an object mainly depends on two main elements like its own electric charge and relative location through other objects which are electrically charged. The Spinning of magnetic field source. Both pulleys, P2 and P3, are mounted on a piece of wood, as seen in the photos, Figures 5a, 5b, 5c, 5d, 5e and 5f show the pulley P4, made up of 3 CDs spaced by two plastic covers, one of the spaces has been reserved to place the nylon rope that supports the mass m, Figures 6a, 6b and 6c show pulleys P1, P2, P3 and P4 fully assembled, Finally we put everything together and as a result we have the system shown in figures 7a to 7i. The primary function of a belt is to transfer power (rotary energy) from one source to another. The tides. We can calculate gravitational potential energy by multiplying the mass of the book times the constant for gravity times the height of the book. Kinetic energy can be found using the formula: KE=12mv2 m = mass (kg) v = velocity (m/s) Gravitational potential energy can be found using the formula: W = mgh = mgh In the figure shown, we can see that the relationship between the radius of the pulley that is on the motor shaft and the radius of the following pulley (P2) is: K1 = R / r1, where K1 is the ratio factor between pulleys P1 and P3, R is the radius of pulley P3 and r1 is the radius of pulley P1.
