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.
i agree with colby
Colby says because it stopped because of unseen forces
Keegan is right because you need force to push the car or it will be come inrtia.
keegan was right because there was no force pushing the car so the car would not move.
I 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.
I agree with Colby because Friction might have stopped the Model Car and the Air Resistance also might have stopped the Model Car.
I 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.
I 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.
I 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.
I agree with Keegan, because there was nothing making it keep going so eventually the car would stop.
I agree with Keegan because the car didn't have anything force pushing on it.
Colby, because it stopped because drag.
Keegan is right because, there was no force to push it.
Colby says because it stopped because of unseen forces
I 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.
I believe Colby
there was no foruse
Keegan Is right because there is nothing pushing on it anymore.
keegan is right It has nothing to keep it going
I agree with Keegan because after the car was pushed there is no more force pushing on it.
i belive keegan
I agree with Colby, because there is always air pushing on something, there were just unseen forces.
Keegan was right because there was no force pushing the car.
I think Keegan was right
keegan was right the car has no force pushing it
I agree with with keegan because when u push the cart is a force and it stops when we stop pushing on it.
I agree with keegan because the force of someone pushing the car or aceleration has worn off.
Team Frost for dayz.
I agree with Colby bc go TEAM COLBY
Colby because ghost are scary
team ryder
Frosty is right.
#TEAM KEEGAN ALL THE WAY.
Team keegan
Keegans never right #TEAM COLBY
GO TEAM COLBY!!!!! It stop going because the gravity was pushing down on it.
I agree with Keegan because after the car was pushed there is no more force pushing on the car.
I 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.
Jealous? You better be.
Keegan was right because there was no force
The carpet could be friction
keegan
Team Keegan.
Keegan 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.
I agree with Keegan because there is no more force pushing the car.
I agree with keegan because the force of someone pushing the car or aceleration has worn off.
I agree with neither they're both awful. Friction is the reason the cars stopped.
Keegan because team Keegan
keegan wins
I agree with Colby because the Air Resistance might have stopped the Model Car.
keegan because i like him better
Keegan because your push has pretty much run out so it would stop easily
Keegan is right because the car had nothing pushing on it to keep it going.
I agree with Keegan.
Colby because because or particles in the air.

brap
Neither 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.
I agree with keegan because the car would stop because it doesn't have anything pushing it.
I agree with colby because the unseen forces that he is talking about is inertia
Keegan is right because there is nothing pushing on the car to keep it moving
I 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.
Keegan because gravity
Keegan is right cuz there was nothing pushing it
I agree with Keegan because there was nothing pushing it
I agree with Keegan.
COLBY IS WRITE
i agree with colby because what if there was a strong gush of wind..
The car stopped because it didn't have enough momentum to continue across the friction-ridden carpet. So, I agree with Colby.
