In physics, Mr Fullerton shows us how throwing a ball across the room and someone catching has everything to do with physics. As he throws the ball he apply an initial velocity for the ball to go through the air. As he releases the ball gravity as a force acts upon the ball and starts to pull it down. as it keeps going air resistance slows its velocity for who ever to catch it. As the ball is caught an equal and opposite reaction is applied to the ball causing it to come to a complete stop and for it to not move anymore. The ball shows how the whole process works and how it can show the diagram of physics to the students.
