While walking


I push the ground...means apply force and that is=mass of ground ×accn of ground....but accn is 0..does that mean I applied 0 force??? definitely not because ground also pushed me in opposite direction (that's how we walk right??push ground backwards and ground pushes us forward)...so there must have been a force that I applied to ground(by 3rd law)




I remember asking the same question in 9th standard and I even got the answer for it(by myself when I thought a lot)...but seems like I forgot??
