kenny1999 Posted May 19 Share Posted May 19 We know that if something is fixed to the ground and we give force to it, then it will give reaction force in equal amount. How about if "something" isn't fixed, e.g. a toy truck? When we push it for an instant, does the toy truck at the same time give reaction force back to the us? Does it only give reaction back for the time they touch each other? Is my concept correct? Link to comment Share on other sites More sharing options...
