Theoretically, friction force should not depend on the sliding velocity. For polymers, however, this statement is only true if the contact temperature grows negligibly; the relaxation behavior of the surface material, as a result, does not change. Usually, however, there is a complex dependence...
A force is a push or pull that acts on an object A force can cause a resting object to move, or it can accelerate a moving object by changing the object’s speed or direction
A hand pulls the block with a dynamometer, which shows the value of the pulling force. Simultaneously, a force–time diagram is displayed as shown in Fig. 1. Fig. 1 GeoGebra simulation of friction used in the study. Overview of picture of block and hand, sliders and graph after the ...

As a result, the drag force F is found [36,37] to be given (1) by the dynamic part scaling as V2 governed by the momentum transfer associated with collisions between the obstacle and cluster of grains ahead of it and (2) by the static part F0 governed by the friction force (...

4. Reflection: When light bounces off a surface and comes back to our eyes, we see a reflection. 反射:当光线从表面反射回来进入我们的眼睛,我们就会看到反射。 5. Friction: It's the force that happens when two surfaces rub against each other, making it harder to move. ...
