Friction and Forces
You roll a model car down the hallway. The car comes to a stop without hitting anything. Keegan says that the car stopped because there was no force pushing on it. Colby says that it stopped because of unseen forces. Who do you agree with and explain why you agree.
Keegan is right because the car had nothing pushing on it to keep it moving.
ReplyDeletei agree with colby
ReplyDeleteColby says because it stopped because of unseen forces
ReplyDeleteKeegan is right because you need force to push the car or it will be come inrtia.
ReplyDeletekeegan was right because there was no force pushing the car so the car would not move.
ReplyDeleteI agree with both boys because yes, there was no one pushing the car, but there was also an unseen force to stop it. If there is a hill going up, gravity will bring the car to a stop. But if you pushed the car up the hill, it would keep going. So both boys are right.
ReplyDeleteI agree with Colby because Friction might have stopped the Model Car and the Air Resistance also might have stopped the Model Car.
ReplyDeleteI would agree with Keegan, because I don't believe there would be unseen forces to stop the car, but if there isnt any forces pushing the car it can't be rolling by itself.
ReplyDeleteI agree with Colby because friction is acting on the car. You cannot see friction itself, but you can see it happening to an object. I agree with Colby because a force is pushing on an object all the time whether it's friction or gravity or a human pushing it forward.
ReplyDeleteI agree with Colby because the gravity is pushing on it in the opposite side of the car the model with the block in front of it made the car go a half the then the regular one because the force pushing on it is more because the force keeps pushing on it a little further then the first one.
ReplyDeleteI agree with Keegan, because there was nothing making it keep going so eventually the car would stop.
ReplyDeleteI agree with Keegan because the car didn't have anything force pushing on it.
ReplyDeleteColby, because it stopped because drag.
ReplyDeleteKeegan is right because, there was no force to push it.
ReplyDeleteColby says because it stopped because of unseen forces
ReplyDeleteI agree with Colby because there was force pushing on the car, that force was air. When the car is driving the air is pushing on the car.
ReplyDeleteI believe Colby
ReplyDeletethere was no foruse
ReplyDeleteKeegan Is right because there is nothing pushing on it anymore.
ReplyDeletekeegan is right It has nothing to keep it going
ReplyDeleteI agree with Keegan because after the car was pushed there is no more force pushing on it.
ReplyDeletei belive keegan
ReplyDeleteI agree with Colby, because there is always air pushing on something, there were just unseen forces.
ReplyDeleteKeegan was right because there was no force pushing the car.
ReplyDeleteI think Keegan was right
ReplyDeletekeegan was right the car has no force pushing it
ReplyDeleteI agree with with keegan because when u push the cart is a force and it stops when we stop pushing on it.
ReplyDeleteI agree with keegan because the force of someone pushing the car or aceleration has worn off.
ReplyDeleteTeam Frost for dayz.
ReplyDeleteI agree with Colby bc go TEAM COLBY
ReplyDeleteColby because ghost are scary
ReplyDeleteteam ryder
ReplyDeleteFrosty is right.
ReplyDelete#TEAM KEEGAN ALL THE WAY.
ReplyDeleteTeam keegan
ReplyDeleteKeegans never right #TEAM COLBY
ReplyDeleteGO TEAM COLBY!!!!! It stop going because the gravity was pushing down on it.
ReplyDeleteI agree with Keegan because after the car was pushed there is no more force pushing on the car.
ReplyDeleteI agree with neither of them. I am always correct. Perhaps the illuminati is at work? Nah, I doubt it. I'd rather believe that I'm actually a dolphin and I'm always the most fabulous one in the room when I enter.
ReplyDeleteJealous? You better be.
Keegan was right because there was no force
ReplyDeleteThe carpet could be friction
ReplyDeletekeegan
ReplyDeleteTeam Keegan.
ReplyDeleteKeegan is the best. but he lost to Colby because Colby went first and Colby's car is fat! But Keegan is right. #i love Colby. #i love Keegan.
ReplyDeleteI agree with Keegan because there is no more force pushing the car.
ReplyDeleteI agree with keegan because the force of someone pushing the car or aceleration has worn off.
ReplyDeleteI agree with neither they're both awful. Friction is the reason the cars stopped.
ReplyDeleteKeegan because team Keegan
ReplyDeletekeegan wins
ReplyDeleteI agree with Colby because the Air Resistance might have stopped the Model Car.
ReplyDeletekeegan because i like him better
ReplyDeleteKeegan because your push has pretty much run out so it would stop easily
ReplyDeleteKeegan is right because the car had nothing pushing on it to keep it going.
ReplyDeleteI agree with Keegan.
ReplyDeleteColby because because or particles in the air.
ReplyDelete#TEAMFROSTY
brap
ReplyDeleteNeither of them are correct. Friction from the cras wheels slow it down to a stop. An object in motion must stay in motion until an outside force stops it. Wind resistance and friction are these forces.
ReplyDeleteI agree with keegan because the car would stop because it doesn't have anything pushing it.
ReplyDeleteI agree with colby because the unseen forces that he is talking about is inertia
ReplyDeleteKeegan is right because there is nothing pushing on the car to keep it moving
ReplyDeleteI would agree with Keegan, because I don't believe there would be unseen forces to stop the car, but if there isnt any forces pushing the car it can't be rolling by itself.
ReplyDeleteKeegan because gravity
ReplyDeleteKeegan is right cuz there was nothing pushing it
ReplyDeleteI agree with Keegan because there was nothing pushing it
ReplyDeleteI agree with Keegan.
ReplyDeleteCOLBY IS WRITE

ReplyDeletei agree with colby because what if there was a strong gush of wind..
ReplyDeleteThe car stopped because it didn't have enough momentum to continue across the friction-ridden carpet. So, I agree with Colby.
