Spring balance measures frictional force | Friction | Physics

The force required to move a wooden plank can be measured using a spring balance as shown in the video. The force without any additional weight is about 100 grams. Start adding weight to the plank, try to move it, and measure the force under which the plank just begins to move. As you add more weight, it becomes clear that the amount of force required keeps increasing. This is because the weight pushing the plank downwards increases the frictional force between the plank and surface, and so requires a greater force to overcome it.

thank u so much sir. I have an school assignment to do and this was my assignment. thank so much

Pls give the answer why friction oppose the motion

Friction opposes only relative motion
Friction sometimes provide body to move then friction and motion in the same direction

My teachers sent this . Thank goodness they did !!

[liv]

this helped me much with my homework! tysm 😁

[ANJALIKUMARI-zwqf]

Thanku much sir my concept is clear now due to this video

[matt-dw]

thank you so much, this helped me with my physics project!

[iamcookie]

Thanks for the video sir. It is helpful for my coming exams

[MubasharBajwa-iqmc]

Perfect video but unfortunately due to my limited knowledge I cannot show this to anyone because it may develop misconception about Newtons and Grams.

Can you please clear me on

Why you are using the grams to measure the force instead of Newtons?

[loveandpeaceforever]

it is easier to move an empty suitcase cause the mass is less, thus the friction is less

[gauraangsingh]

thanks a lot sir. this helped me a lot for my practical.

[chiragbhatnagar]

can u tell the relation between the weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance

[zeezeezoo]

grams is not a measure of force, maybe u should try researching this further

I don't understand what is really happen there
