*The '''centre of mass''' plays a critical role in the analysis of motion and dynamics.
*The '''centre of mass''' is important in sports and biomechanics for optimizing performance and balance.
===Method to find the Centre of Mass of a Lamina===
#Hang the [[lamina]] from a point.
#Hang a [[Plumb Line|plumb line]] from that point.
#Draw a line down the [[lamina]] following the string of the [[Plumb Line|plumb line]].
#Hang the [[lamina]] from a second point.
#Repeat steps 2 and 3.
The point where the lines cross will be the '''centre of mass'''.
A third line can be drawn to confirm this location.
===Examples===
*The centre of [[mass]] of a uniform rod is at its midpoint.
*Athletes adjust their centre of [[mass]] to improve performance in activities like high jumping and gymnastics.
