investigation of uniformly accelerated rotational motion
- The resistance with which a rigid body opposes a change to its rotation is indicated by the mass moment of inertia.
- It is a measure of the inertia of a body in rotation.
- Using the TM 612kinetic model, we can conduct basic experiments on uniformly accelerated rotational motion.
- The experimental unit comprises a flywheel with shaft, a cable and a set of weights.
- The shaft forms the axis of rotation in the centre of gravity of the flywheel.
- It is mounted on two bearings.
- One end of the cable is attached to the shaft.
- A weight is attached to the other end.
- The attached weight sets the flywheel in a uniformly accelerated motion.
- The time needed to roll down is measured and compared to the times for other weights.
- The mass moment of inertia of the flywheel is calculated from the measured time, the mass of the flywheel and the acceleration distance.
- The experimental unit is designed to be fixed to a wall.
