The complete set of this experiment was mainly consisted of four parts. The first experiment were to confirm that the angular momentum would be conserved when there is no external torque exerting on the mechanical system. The second experiment were to verify that the rotational kinetic energy can be adopted to the energy conservation principle successfully. The third experiment were to show that the moment of inertia was indeed proportional to the square of the distance of the mass to the axis of rotation. The fourth experiment was to show that at the elastic collision, the conservation of the angular momentum would be satisfied.

본문내용

In the first experiment, we could verify that when the two rotating disk were to be go under the collision, the total angular momentum ought to be conserved since there is no external torque exerting on the system. In the second experiment, we could conclude that in the regime where the rotation is involved. then the concept of the rotational kinetic energy has to be included so as to satisfy the energy conservation principle. In addition, the rotational kinetic energy can be calculated by the equation , where is the moment of inertia and is the angular velocity. In the third experiment, we could verify that the moment of inertia can be derived by dividing the magnitude of the torque by the angular acceleration, that is, . Moreover, the magnitude of the was proportional to the square of , which is the distance of the mass from the axis of rotation. The fourth experiment enabled us to conclude that in the collision, the rotational momentum is fairly conserved while the rotational kinetic energy may not be conserved during an inelastic collision.
