I have recently been doing some work around Newtons third law. And I was thinking about a question revolving around the topic. It is a common question of 'how can we move at all if all forces are equal and opposite, all movement must cancel out in that case'how can we move at all if all forces are equal and opposite, all movement must cancel out in that case. I searched it up and all answers say 'Action and reaction forces do not cancel each other because they act on different objects.' However I do not quite undestandunderstand why this is the case. At first I thought it was due to a persons reaction to a force. For example lets take someone pushing against a ball, the person does not move due to the friction force against him on the ground; the ball moves because there is no frictional force applied back to it. Though, I am unsure if this is the correct understanding.
I'd really appreciate if someone could give a more descriptive answer on why Newtons Third Law does not cancel out. Or at least give a real life example of why it's the case.
Sorry it's a simple question but i'd like to have a clearer understanding.
Thanks!
