Enter a value for all fields
The Center of Mass calculator computes the center of mass between two loads (masses).
INSTRUCTIONS: Choose units and enter the following:
- (m1) Mass 1
- (d1) Distance to Mass 1
- (m2) Mass 2
- (d2) Distance to Mass 2
Center of Mass (COM): The distance is returned in meters (m). However, this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The Center of Mass equation computes the distance from an origin that represents the center of mass for two objects. This is commonly used to determine ideal load balance in aircraft and space craft.
The formula for Center of Mass is:
`COM = (m1*d1+m2*d2)/(m1+m2)`
where:
- COM = Center of Mass
- m1 = mass of object 1
- d1 = distance to object 1
- m2 = mass of object 2
- d2 = distance to object 2
