Which of the following is a measure of the inertia of an object?
IInertia is the resistance of an object to change in momentum, which can be measured as the force applied to an object divided by acceleration.
So Inertia=F/a
So we measure the inertia of an object in Kilogram or any other unit of mass.
The inertia of an object is the measure of its resistance to a change in its state of motion. How can the inertia of the cart-pulley-hanging mass system be increased?
One simple way to measure the moment of inertia of an irregular object is shown in the diagram. The object is mounted on a frictionless axis. A light string is wrapped around the object, passes over a light pulley (so it has negligible moment of inertia itself), and then connected to mass M = 40.6 kg. The system is released from rest. After mass M has fallen distance 4.05 m it is moving 2.67 m/s and the object has reached...
Which of the following statements is false? The moment of inertia of an object depends on the location of its axis of rotation The moment of inertia of an object depends on the angular acceleration of the object as it rotates An object can continue to rotate in the absence of torque An applied net torque may reduce the angular speed of an object Of the particles that make up an object, the particle with the smallest mass may contribute...
Part A On which of the following does the moment of inertia of an object depend? Check all that apply. linear speed linear acceleration angular speed angular acceleration total mass shape and density of the object location of the axis of rotationTo understand the definition and the meaning of moment of inertia; to be able to calculate the moments of inertia for a group of particles: to relate moment of inertia to kinetic energy .
Mass is a measure of _______. the force on an object due to gravity the weight of an object, and is measured in pounds (lbs) the quantity of matter in an object and the inertia of the object the quantity of space an object occupies
Students run an experiment to determine the rotational inertia of a large spherically shaped object around its center. Through experimental data, the students determine that the mass of the object is distributed radially. They determine that the radius of the object as a function of its mass is given by the equation r = km², where k = 3 Which of the following is a correct expression for the rotational inertia of the object?
1. The moment of inertia (sometimes referred to as a “swing weight”) is a measure of the resistance to rotation about a particular axis. It is often expressed as Ia = mka2 where m is the mass of the object and ka is the radius of gyration about the axis of rotation. The radius of gyration ka for the arm about its COM = 0.368*(arm length). Compute the moment of inertia of the arm in the extended position about its...
If an object has a moment of inertia 28 If an object has a moment of inertia 28 kg.m2 and the magnitude of its rotational angular momentum is 77 kg • m²/s, what is its rotational kinetic energy? and the magnitude of its rotational angular momentum is 77 kg what is its rotational kinetic energy? Krot =
Physics problem A 3-dimensional object actually has THREE principle moments of inertia - the moments of inertia about the three mutually perpendicular "principle" axes. Take a rectangular book or object that has three different dimensions (length, width and height), so that it has three different moments of inertia, and try to spin it around the three principle axes (the axes that are perpendicular to each face of the object and pass through the center of it). Only one axis produces...
A constant net torque is applied to an object. Which one of the following will NOT be constant? A) Angular acceleration B) Angular velocity C) Moment of inertia D) Center of gravity
