Typical examples of inertia include a passenger's body slightly moving backwards when a vehicle suddenly starts; a passenger's body leaning forward when a moving vehicle stops and a passenger's body jerking to the side when a vehicle maneuvers a sharp turn. Inertia is one of the defining characteristics of matter, which refers to the tendency of any object to remain at rest or continuously move along a straight line.
Know MoreInertia is classified into three types: inertia of rest, inertia of motion and inertia of direction. A leaf falling from the branch of a tree that is disturbed by a strong wind is an example of inertia of rest. A person that falls down after carelessly jumping off a moving train is an example of inertia of motion. Mud that sticks to rotating wheels and are thrown tangentially is an example of inertia of direction.
Learn more about Motion & MechanicsInertia is a scalar, something that only has a magnitude, and is defined as the resistance of an object to its state of motion, which also includes the state of rest. An object's mass is a measure of its inertia. Momentum is a vector, something that has a magnitude and direction. It's a measure of an object's motion and is dependent on the product of an object's mass and velocity.
Full Answer >The law of inertia is a fundamental physics principle used to describe how an object behaves in motion or at rest, particularly when forces are applied to it. The object can be anything that has mass.
Full Answer >The moment of inertia of a solid cylinder is equal to one half of the mass multiplied by the square of the radius. This equation should be used to find the cylinder's moment of inertia with respect to the z-axis, or the plane parallel to the cylinder's height.
Full Answer >A sitting plane on a runway has a higher inertia than a moving car. In order to change the inertia of rest of the sitting plane, significantly more energy is required than to change the inertia of motion of the moving car.
