When a body is free to rotate around an axis, torque must be applied to change its angular momentum. The amount of torque needed to cause any given angular acceleration (the rate of change in angular velocity) is proportional to the moment of inertia of the body. Moments of inertia may be expressed in units of kilogram metre squared (kg·m ) in SI units and pound-foot-second squared (lbf·ft·s ) in imperial or US units. Web惯性矩(moment of inertia of an area)是一个几何量，通常被用作描述截面抵抗弯曲的性质。惯性矩的国际单位为(m4)。即面积二次矩，也称面积惯性矩，而这个概念与质量惯性矩（即转动惯量）是不同概念。 ottery garden centre taunton
