2 Mechanics 2.5 Rotational Motion
Moment and angular momentum
P2131500
Angle of rotation as a function of time with uniformly accelerated rotary motion for m = 0.01 kg, r = 0.015 m.
Principle
Light barrier with counter
The angle of rotation and angular velocity are measured as a function of time on a body which is pivoted so as to rotate without friction and which is acted on by a moment. The angular acceleration is determined as a function of the moment. Tasks With uniformly accelerated rotary motion, the following will be determined: 1. 2. 3. 4.
the angle of rotation as a function of time, the angular velocity as a function of time. the angular acceleration as a function of time, the angular acceleration as a function of the lever arm.
