Specification Brand : FYYKXWD BulletPoint1 : The friction force demonstrator is a demonstration instrument in middle school physical mechanics. This instrument clearly demonstrates the existence of sliding friction and static friction, and the factors that determine their size. BulletPoint2 : It shows that the magnitude of sliding friction is related to the roughness of the between two objects; BulletPoint3 : The magnitude of sliding friction has nothing to do with the relative motion of the two objects; BulletPoint4 : When two objects are in with each other and have a tendency to move, there is static friction, and the magnitude of the static friction increases with the increase of the external force. BulletPoint5 : Prove that the maximum static friction force is greater than the sliding friction force.

This instrument clearly demonstrates the existence of sliding friction and static friction, and the factors that determine their size. 1. When two objects are in with each other and move relative to each other, sliding friction exists; 2. Prove that the magnitude of sliding friction is proportional to pressure; 3. Explain that the magnitude of sliding friction is related to the roughness of the between two objects; 4. The magnitude of sliding friction has nothing to do with the relative motion of the two objects; 5. When two objects are in with each other and have a tendency to move, there is static friction, and the magnitude of the static friction increases with the increase of the external force. 6. Prove that the maximum static friction force is greater than the sliding friction force.
2. Main performance indicators: 1. Rated voltage: ~220V 50Hz 2. Motor power: 50W 3. Speed regulation: stepless speed regulation 4. Insulation resistance is greater than 20 ohms
1. When using, please pay attention to the voltage consistent with the voltage of the instrument. 2. The instrument must be placed stably (horizontally), and the movements must be balanced during demonstration, and be put down and picked up gently. 3. When starting the motor, it is best to use fast gear and adjust from fast to slow. 4. After the demonstration, remove the demonstration dynamometer, put the instrument away, and store it in a ventilated and dry place.
