... I can calculate acceleration from data about changes in motion over time. I can recognize that any change in motion is a consequence of unbalanced forces. I know that a change in motion (acceleration) is always in the direction of net force. I can show that acceleration is directly proportional to n ...

12.3 Newton`s 3rd Law of Motion
... According to Newton’s 2nd law, if mass increases and force stays the same, acceleration decreases. The same force acts on both Earth and your pen but Earth has such a large mass that its acceleration is so small you don’t notice it. ...

... What happens if you are standing on a skateboard or a slippery floor and push against a wall? You slide in the opposite direction (away from the wall), because you pushed on the wall but the wall pushed back on you with equal and opposite force. Why does it hurt so much when you stub your toe? When ...
