Inertia and Newtons laws of motion
... a restatement of Galileo’s idea that a force is not needed to keep an object moving. Galileo argued that only when friction is present is a force needed to keep an object moving. Galileo stated that if friction were entirely absent, a ball moving horizontally would move forever at the same speed ...

Solutions for class #7 from Yosumism website Problem 44:
... One can derive the frequency of small oscillation for a rigid body in general by using the torque form of Newton's Laws: . (I is moment of inertia, r is moment arm) In this case, one has a constant downwards force , which acts at a moment arm angle . Thus, , where the approximation works if ...

Moments of INERTIA
... Moments of Inertia • Moments of Inertia is an object’s resistance to change in it’s rotational motion – It is how well an objects resists angular acceleration – Moments of Inertia play the same roles in rotational motion as mass does in translational motion. ...
