Rotational Motion (Kinetics, Energy, Work, Power) - Coggle Diagram
Rotational Motion (Kinetics, Energy, Work, Power)
Torque
Properties
-
Direction: Shown using arrows (CW, CCW)
Formula
T = F x R. T: Torque[Nm], F: Force[N], R: distance from the axis of rotation [m]
-
-
Moment of Inertia
Definition: The resistance of an object to changes in its rotational motion (analogous to mass in linear motion)
Formula: I = m x r^2. I: Moment of inertia [kg.m^2]. m: Mass[kg]. r: Distance from the axis of rotation [m].
-
Moment of Inertia for Common Objects: Include specific formulas for discs, spheres, etc. (optional branch if needed)

Examples
Example 4: Flywheel with a torque of 35Nm completing 200 revolutions. Convert revolutions to radians, then calculate work done.

Example
Example 5: An electric motor with 80Nm torque and 1500 rpm. Convert rpm to rad/s, then calculate power
