Rotational Dynamics
Explore the physics of spin by applying torque to a rigid body and observing how its rotation changes based on its mass distribution.
Topic Overview
In linear motion, force causes acceleration (F=ma). In the spinning world, Torque (τ) causes Angular Acceleration (α). Torque is a twisting force that depends on how much force is applied and how far from the pivot it's applied (τ = rF). An object's resistance to spinning is its Moment of Inertia (I), which depends on its mass and how that mass is distributed.
What You Can Do
- Apply torque by setting a force and its distance from the pivot.
- Observe how a larger force or distance creates a larger torque.
- Add masses to the ends of the rod to increase its moment of inertia.
- Watch how the same torque produces less acceleration on an object with higher inertia.
