thanks sir,it really helped

the other path should be -12J because gravity acts in the same way as direction but it's still not equal to the other path so it's the same idea :D

THANK YOU SO MUCH FOR YOUR VIDEOS. AND I MEAN ALL OF THEM

@omoragan I think both his x-axis and y-axis are on a horisontal plane. In that case he is correct.

You are calm and it's very good + You explain very well. Thanks

No, he did it right, it is path-dependent like he said, Friction always acts in the opposite direction of motion, so it is always negative.

Thanks for the post....not the whole concept makes senses to me

@yourname240....I agree with u it should be +2j

[yourname240]

isn't part 8:43 supposed to be +2J or work, bc the force is in the same direction of the friction?

@yourname240 no i think; when you look at air giving the friction, it will have friction going down.
