Abstract

The invention discloses an interesting experimental device for demonstrating the action of a frictional force. The device comprises an anti-skid plate; the top of the anti-skid plate is sequentially provided with a first fixing plate and a second fixing plate from left to right; and the side left of the top of the first fixing plate and the right side of the top of the second fixing plate are fixedly connected with a first vertical plate and a second vertical plate respectively. According to the device of the invention, the first fixing plate, scale marks, a first connecting rod, a first connecting plate, a first friction block, the second fixing plate, a second friction block, a second connecting plate, a second connecting rod, a second tension meter, a second hanging ring, the second vertical plate, the first vertical plate, a first tension meter, and a first hanging ring are adopted. With the interesting experimental device for demonstrating the action of the frictional force of theinvention adopted, the problem that an existing interesting experimental device for demonstrating the action of the frictional force is inconvenient for a user to use can be solved, students can observe experimental phenomena more intuitively, the interest of the students in learning can be improved, and the teaching efficiency of the user can be improved.

Description

Technical field [0001] The invention relates to the technical field of teaching aids, in particular to a fun experimental device demonstrating the action of friction. Background technique [0002] The force that hinders the relative motion (or relative motion trend) of an object is called friction. The direction of the friction force is opposite to the direction of the relative motion (or relative motion trend) of the object. The friction force is divided into static friction, rolling friction, and sliding friction. When an object slides on the surface of another object, the friction between the contact surfaces that hinders their relative movement is called sliding friction. The magnitude of sliding friction is related to the roughness of the contact surface and the pressure. The greater the pressure, the object contacts The rougher the surface, the greater the sliding friction generated. The methods to increase the beneficial friction include: increase the pressure, increase th...
