According to newtons third law of motion we cannot throw a basaball?

according to newtons third law of motion we are not able to throw a baseball because everything has an equal and opposite force. so according to this all the forces will cancel out and the ball would not be able to move. can someone please tell me why this isnt true? thanks!According to newtons third law of motion we cannot throw a basaball?That isn't true...common misconception.



You need to read Newton's third law more carefully if you think it is.



The two equal and opposite forces in Newton's third law DO NOT ACT on the same object. They act on two different objects.





Considering you throwing the baseball, during contact with your hand, the following is true:



You apply a force on the baseball

The baseball applies the same force BACK on you.





If you aren't bracing yourself to the field, you will recoil backwards as a result. In truth, all of Earth recoils backwards, but because Earth has tremendous inertia (and because actions elsewhere that might contradict it occur), it isn't noticeable.
