It's easier to pull a body than pushing it. Since, more frictional force is applied by the surface on the body when it's trying to move.

[@krishnaagrawal997]

10:38:30 the direction of force and displacement is opposite so the work done by resisting force is negative

8:33:20 Sir jb theta 37 degree ka hai tb to aise hi pta chl jaa rha h ki uska hypotaneous 5 metre ka hoga to fir 1st equation of motion q use kre ?

[@MagnetBrainsEducation]

Thanks for your comment! This is a great question! When theta is 37 degrees, the hypotenuse will be 5 meters, so you don't use the first equation of motion in this case. Instead, you can use the Pythagorean theorem to solve for the side lengths.

[@harshitsrivastava4329]

Thanks sir

[@gauravtripathi4788]

sir as you said that if the object's speed will increase it will be positive work done and if it would decrease it will be negative work done but when we see a fast moving object getting slowed at some extinct ...... can we say that firstly there was positive work done and then negative came?
