How to Calculate the Physics of Pulley Weights
The physics of pulley weights can be determined using Newton's Second and Third Laws of motion. Newton's Second Law states that the net force acting an object is equal to the product of its acceleration and mass. Newton's Third Law states t... Read More »

What are the uses of double pulley in physics?
The amount of force required to lift a weight is inversely proportional to the number of suspension lines. A multiple pulley system allows the load to be distributed across several lines and greatly reduces the amount of force required to l... Read More »

Hello Linda, When both bobs are hanging still, the tension in the string above each is, of course, equal to the weight of the bob. When one is swinging, it's swinging in an arc, so it needs centripetal force to force it into the circular pa...

Not exactly sure what you are looking for... Pulley systems are essentially simple machines that enable work to be done with less force over a greater distance. Here is the formula: W=Fd So to do some amount of work (lifting a box), you can...

T – m2g = m2a, m1g – T = m1a, a = (m1-m2)g / (m1 + m2) = (5.29-2.55)(9.8)/(5.29+2.55) = (2.74/7.84)(9.8) = 3.425 m/s^2 Y = 0.5at^2 = 0.74 = 0.5(3.425)t^2, => t = sqrt{0.74)2/(3.425)} t = sqrt{4.32} = 2.1 s W = (m1-m2)ad = Iw^2, v =rw, w =v/...

think of it horizontally. 9.8x5 <-- [ 5 kg ]-------------[3 kg] --> 9.8x3 you have a 49N force left, and a 29.4N force right (if you use 10 as gravity, its 50 and 30, which is easier) so, your net force is 50-30=20 so 20=MA your masses toge...
