define and explain the moment of inertia?
Answers
Answer:
a quantity expressing a body's tendency to resist angular acceleration, which is the sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation.
Answer:
Moment of inertia can be defined as a quantity that expresses a body’s tendency to resist angular acceleration, which is equal to the sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation. Its formula is given by I = L/ω (where I denotes the inertia, L denotes the angular momentum, and ω denotes the angular velocity). Moment of Inertia is also known as the angular mass or rotational inertia. The SI unit of moment of inertia is kg m2.
Moment of inertia is usually specified with respect to a chosen axis of rotation. It mainly depends on the distribution of mass around an axis of rotation. MOI varies depending on the axis that is chosen.
