The centripetal force formula can be directly summarized by the centripetal force demonstrator. Precautions: 1. The base must be balanced and kept level when the instrument is in use. 2. Before using, you need to add a little oil to the guide rod at the end of the cylindrical body to reduce friction. 3. When the shaft is tilted, try to apply force evenly and periodically. 4. The instrument should be stored in a ventilated and dry place to prevent corrosion of the surface coating.
Uses: Verify the centripetal force formula experiment.
Principle: According to the centripetal force formula: F=mwr=4m2n2mr
In the experiment, the object moves in a uniform circular motion in the horizontal plane, and its mass is measured as m (kilo) rotation radius r (meter) and rotation speed n (rev / sec).
The centripetal force (Newton) can be calculated by the above formula, and then compared with the spring force measured directly by the spring to the same tensile force, the above formula can be verified.
