Description

technical field [0001] The invention relates to a teaching instrument, in particular to a teaching instrument for friction experiment. Background technique [0002] Friction is a term in classical mechanics, which refers to the elastic force of two objects in contact with each other. When they are about to move or have a tendency to move relative to each other, a force that hinders relative movement will be generated on the contact surface. It is called frictional force. Objects are also subject to frictional force when moving in liquid and gas. As a metaphor the word friction is also often used in everyday life to describe forces that impede progress. [0003] There are many ways to verify the influence of friction. Generally, it is compared by observing the final displacement of a moving object with the same acceleration under different friction forces. Existing teaching instruments are difficult to accurately apply the same acceleration during experiments, and the manufa...
