Rigid body — definition?
An idealized solid with fixed inter-point distances.
Rigid Body — definition?
An undeformable solid object with constant distance between points.
Torque — role?
Causes rotation by producing angular acceleration.
Torque — role?
Causes angular acceleration in a rotating body.
Equation of rotational motion?
τ = Iα, torque equals moment of inertia times angular acceleration.
Friction — effect on rotation?
Resists motion and causes damping.
Angular momentum — conservation?
Constant in isolated systems without external torque.
Rolling motion — key condition?
No slipping between rolling object and surface.
Center of mass — purpose?
Represents overall mass distribution's average position.
