==Key Stage 5==
===Meaning===
The '''centre of mass''' of a body is the point through which a single [[force]] on the body has no turning effect.
===About the Centre of Mass===
*The '''centre of mass''' is the average position of all the [[mass]] in an [[object]].
*For a symmetrical [[object]] with uniform [[density]], the '''centre of mass''' is at its geometric centre.
*The location of the '''centre of [[mass]]''' affects the stability of an [[object]].
*In irregularly shaped objects, the '''centre of mass''' may not coincide with the geometric centre.
*The '''centre of mass''' can be outside the physical body in certain configurations.
*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.
===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.
