It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. Calculations in mechanics are often simplified when formulated with respect to the center of mass.
This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. In physics, the center of mass of a distribution of mass in space (sometimes referred to as the balance point) is the unique point where the weighted relative position of the distributed mass sums to zero. (mass of item 1 + mass of item 2 + mass of item 3) = Item 3 has a mass of 25kg and a distance of 12 meters.Ĭenter of Mass= (mass of item 1)(distance of item 1) + (mass of item 2)(distance of item 2)+ (mass of item 3)(distance of item 3)/ Since the unit masses cancel out in the calculation, the resultant value is in whatever units the distance is entered in.Ĭalculate the center of mass item 1 has a mass of 20kg and a distance of 1 meter, item 2 has a mass of 15kg at a distance of 7 meters, and Of 3 meters, the center of mass is located at a distance of 3.82 meters. So with one item having a mass of 7kg and being located at a distance of 5 meters and a second item having a mass of 10kg and being located at a distance Thus, knowing theĬenter of mass can come in handy and be very useful when dealing with electronic components such as this.Ĭalculate the center of mass when the mass and distance of one item is 7kg and 5 meters and mass and distance of the second item isĬenter of Mass= (mass of item 1)(distance of item 1) + (mass of item 2)(distance of item 2)/(mass of item 1 + mass of item 2) = Different masses, which cause different weights (w=mg),Įxert different forces (due to the differing masses).
An accelerometer is an electronicĭevice which responds according to different forces upon it. The center of mass can be very useful in electronics because certain electronic components such as accelerometers make However, the standard and scientific unit would be meters (m). If a user just wants to enter,įor example, 3 masses, then he or she just has to enter 3 values and leaveĪny unit can be used to represent X CM, including meters, feet, inches, etc. Object at their various respective distances on the object.Ī user can enter up to 10 masses, with their respective distances, along the object, for this calculator. To use this calculator, the user enters in all the different masses present on throughout a given This is like visualizing the effect of balancingĪ seesaw about a pivot given the two forces or masses present at both ends. The center of mass calculator calculates theĭistance, X CM, where along the object's length, there would be a balancing or equalization of mass from the two end points. This center of mass calculator calculates where the center of mass is located on an object.Īn object can have many different masses distributed throughout it, at different distances along it (the object).
