Formula for translational angular momentum

Click For Summary
SUMMARY

The formula for calculating translational angular momentum is L = I ω, where L represents angular momentum, I is the moment of inertia, and ω is the angular velocity. For different geometric objects, such as a rolling disc or a rolling sphere, the moment of inertia varies, affecting the angular momentum calculation. In rotational dynamics, the relationship between force and torque is expressed as Torque = Moment of Inertia * Angular Acceleration, allowing for substitutions of terms like mass and distance.

PREREQUISITES
  • Understanding of angular momentum and its formula L = I ω
  • Familiarity with moment of inertia for various geometric shapes
  • Knowledge of angular velocity and its role in rotational dynamics

Of a rolling disc? Or a rolling sphere? Its different for every geometric object. The formula is L = I \omega

And for future reference, anything to do with angular dynamics equation can be easily found by using various substiution:

mass = moment of inertia
v = omega
Force = Torque
Distance = Theta
acceleration = angular acceleration

So F = ma, in rotational dynamics is Torque = Moment of inertia * Angular Acceleration.

Just replace all the terms.
