... Example 9 The Moment of Inertia Depends on Where the Axis Is. Two particles each have mass m and are fixed at the ends of a thin rigid rod. The length of the rod is L. Find the moment of inertia when this object rotates relative to an axis that is perpendicular to the rod at (a) one end and (b) the ...

... Stress the reasoning behind each equation, for example, that velocity is a ratio that describes a property of objects in motion. Likewise, acceleration is a time rate of change of velocity, so vf - vi/t not only makes sense but can be reasoned out rather than memorized. Also stress the need to show ...

... If a force acts of a body, the body will accelerate. The ratio of the applied force to the resulting acceleration is the inertia (or mass) of the body. If a torque acts on a body that can rotate freely about some axis, the body will undergo an angular acceleration. The ratio of the applied torque to ...

... Now, stretch the spring as shown, moving the mass to x = A. If the mass is then released from rest, it will oscillate (in the absence of friction) forever between x = ± A. When the spring is stretched an amount x, it feels a restoring force F = -kx that tries to return the system to its equilibrium ...
