If Aaron’s hypothesis is correct, and objects always move in the direction of the unbalanced force exerted on them by other objects and I roll a ball at a velocity where the frictional force exerted by the floor on the ball is stronger than the force exerted by my hand on the ball then the ball should move in the direction that the frictional force of the floor is pushing it (opposite direction of my hand). I think differently. I think that objects sometimes move in the direction of the unbalanced force exerted on them by other objects. If my hypothesis is correct and I roll a ball at a velocity where the frictional force exerted by the floor on the ball is stronger than the force exerted by my hand on the ball then the ball could move in the direction that I’m pushing it in. The procedure that my group executed was pushing a bowling ball down the hallway with our hand. We used a timer to time how long it took the ball to get from one horizontal line on the hallway floor to the next. We started off pushing the ball at a constant velocity so that the ball was getting to each horizontal line in 5 seconds. Then we switched to pushing it at a velocity of -1 second per horizontal line, meaning that the force exerted by the floor on the ball was becoming stronger then the force of my hand. What I observed during the procedure was that the ball was moving in the direction that I was pushing it even when I was pushing it slower and slower (the frictional force was stronger then…
