For a system of particles, the total moment of inertia is calculated by which of the following?

Correct Answer: I_total = Σ(m_i * r_i^2)

Step 1: Understand that the moment of inertia measures how difficult it is to rotate an object around an axis.
Step 2: Recognize that for a system of particles, each particle has its own mass and distance from the axis of rotation.
Step 3: Identify that the moment of inertia for a single particle is calculated using the formula I = m * r^2, where m is the mass and r is the distance from the axis.
Step 4: Realize that to find the total moment of inertia for all particles, you need to add up the moment of inertia for each particle.
Step 5: Use the formula I_total = Σ(m_i * r_i^2), where m_i is the mass of each particle and r_i is the distance of each particle from the axis.

Moment of Inertia – The moment of inertia is a measure of an object's resistance to rotational motion, calculated as the sum of the products of each particle's mass and the square of its distance from the axis of rotation.
System of Particles – A system of particles refers to a collection of individual masses that can be analyzed collectively to determine properties like moment of inertia.
Summation Notation – The use of summation notation (Σ) indicates that the total moment of inertia is found by adding the contributions from all particles in the system.
