Question

write the variation of friction on pushing of heavy box........?...........(it's 4m question) please give more points..........​

Answer 1

Answer:

I will show you a graph on variation of friction while pushing a box. Please refer to the attached photo.

While pushing, until critical force is reached, the friction goes on increasing: this is called static friction.

After it starts moving, friction decreases a little and becomes constant. This is called dynamic friction.

Hope you will be able to understand.
