Mythbusters Lab 2

Myth #2: An object always changes its motion if there is a force exerted on it.

Statement: If an object always changes its motion if there is a force exerted on it by other objects, and we roll a ball at a bottle, then the ball will stop.
The sum of the forces is -Fn1 but the ball rolls through the bottle without changing direction, disproving the myth.

Conclusion:
       My prediction was wrong since the ball rolled straight through the bottle and didn't change direction at all.  I believed that the ball would somewhat change direction, but nothing of that nature happened.  If the ball had hit a wall, then the ball would have bounced back and changed in the complete opposite direction.  This is a commonly believed myth.  When there is a large force at play, but when there is a small force it doesn't affect it at all.  The myth is one of those "no duh" type things, but it turned out to be false.

  1. Not very clear if your point is about the bottle or about the ball.
    Why would the ball stop? What makes you believe that? What would happen if the ball crashes against a wall? will it stop? will it bounce?
    Not clear that you are stating this correctly.
    Also, the conclusion needs more explanation.
    Great editing of the videos.
