I asked students to watch the Three Incorrect Laws of Motion video and to then discuss each one and how they are different that Newton’s Three Laws:
Here is what one students wrote about Newton’s 2nd Law:
[The incorrect law is that ] an unbalanced force causes an object to move with constant velocity (F=mv). This is untrue because F=ma. Changing the force causes the object to accelerate, so the velocity is changing.
It’s interesting, isn’t it?
