Rotational Dynamics of Force - Essay Example

1. Torque. In both three cases,  different magnitudes of torque are applied. This observation is valid and can be explained by the equation where, is the absolute torque applied, the absolute radius, the absolute force applied in the direction of push, and the angle of the swing.

According to the equation, the torque applied increases with an increase in radius.2. Conservation of Angular Momentum. The law of conserva tion of angular momentum states that momentum is conserved when no external force is applied. In all three situations that is, holding hands by my side, stretching my hands, and holding masses on my hands while rotating, the law applies since no external force is applied. The addition of masses increases the torque under the formula L= Iw where I am a function of mass.3. Shape and Momentum of Inertia.

A disk shape produces a low momentum of inertia since it has no hollow space (fully occupied mass towards the center of rotation). According to the equation, and disk processes low inertia under free fall than the ring given a constant kinetic energy.4. Conservation of Angular Momentum (Again)
