In the metric system, weight is measured in Newtons following the equation W = mg, where W is weight, m is mass, and g is the acceleration due to gravitational field On earth, this value is approximately 98 m/s 2 It is important to note that regardless how strong a gravitational field may be, an object that is in free fall is weightless In cases where objects undergo accelerationThis formula uses the fact that the weight of the vehicle is W = mg Work of forces acting on a rigid body The work of forces acting at various points on a single rigid body can be calculated from the work of a resultant force and torque To see this, let the forces F 1, F 2 F n act on the points X 1, X 2 X n in a rigid body · 5 mg/ mg = = % w/w You might check that the other tube wasn't 5 mg/g rather than for the whole tube That would be 05%, the same thing But if your description is correct, there is a 301 difference, and he has reversed which is stronger, quite a serious error, really

· In this formula, W = mg, one can find the mass by rearranging this formul = mThe formula for weight is given by w = mg As weight is a force its SI unit is also the same as that of force, SI unit of weight is Newton (N) Looking at the expression of weight we see that it depends on mass and the acceleration due to gravity, the mass may not change but the acceleration due to gravity does change from place to place To understand this concept let's take this exampleW = mg W = 4800 x 10 = Newtons The tension (T) in the cable acting upwards and given as 60 000N when the elevator starts to move upward, the net force equals the difference in the two forces Using the formula of force, T mg = ma 60 000 48 000 = 4800a 12 000 = 48 00a a = 12 000/4800 = 25 The maximum upward acceleration the elevator can have is 25 m/s 2
