From linear to rotational motion
Stefan Bracher
Linear motion Movement in x, y or z direction
Quantified by: Position x [m], speed v [m/s], acceleration a [m/s 2 ]
Influenced by: Force F [N]
Rotational motion Rotation around the x, y or z axis
Quantified by: Position θ [rad], speed ω [rad/s], acceleration α [rad/s 2 ]
Influenced by: Torque τ [N*m]
(Torque = the ability of a force to turn an object)
Note: Do not give up just because of the greek characters. We use greek characters for rotational things just to
make it look fancy (and because we run out of letters in the latin alphabet)
