The moment is a vector quantity, since it is the tendency of a body to remain in motion. Inertia momentum formula with tabular form
Inertia: Inertia momentum formula with tabular form
Inertia is a scalar quantity since it is the resistance offered by the body to move.
Concept of inertia and Momentum:
The concept of inertia and momentum is regularly confused due to their similar definitions. Inertia is the resistance that a body offers to movement, while momentum is the tendency of a body to continue moving. Let’s look at the differences between the two to better understand the concept.
Below we show you a comparative table with the main differences of these two physical concepts.
|The moment is a vector quantity, since it is the tendency of a body to remain in motion.||Inertia is a scalar quantity since it is the resistance offered by the body to move.|
|The moment is denoted as ‘ p ‘||Inertia is denoted as » I «|
|The momentum of a body of mass ‘m’ moving with a velocity of ‘ v ‘ is calculated as p = m × v||Inertia cannot be calculated using a formula.|
|Linear momentum and angular momentum are the two types of moment.||Inertia of rest, inertia of motion, and inertia of direction are the three types of inertia.|
|The moment depends on the mass and the speed.||Inertia depends only on mass.|
|Full momentum is preserved.||Inertia has nothing to do with the conservation of energy.|
Formula: Inertia momentum formula with tabular form
The formula for moment of inertia is the “sum of the product of mass” of each particle with the “square of its distance from the axis of the rotation”. The formula of Moment of Inertia is expressed as I = Σ miri2.
