Why does it stop?

You roll a model car down the hallway. The car comes to a stop without hitting anything. Cameron  says the car stops because there was no force pushing on it. Emma says it stopped because of unseen forces. Who do you agree with and explain why.

EMMA IS RIGHT because friction is the biggest force that is stopping it.

Cameron Frost said...

I agree with both because they both are causes of friction.

Emma is right.

I agree with emma because friction is what slows stuff down.

Emma because air friction stuff

Emma is right.

I agree with Emma because the unseen force of friction as making it slowly stop.

i agree with emma because friction is a big cause of it.

Emma is right because of friction

I agree with Emma because friction is an unseen force that stops the car.

anthony johnson said...

the friction would make emma right.

Rachel P. said...

I think that Emma is right because the car is also being influenced by other forces like gravity and friction.

Cameron is right because friction stops all forces from pushing the object.

emma is correct because of unseen forces

I agree with both because of friction.

i agree with emma because you push the car down the hallway so there is a push force.

Emma is correct because the unseen forces made it stop?

Unseen forces

LAYSSE said...

I agree with Emma because friction is the way that it slows down.

emma because of air friction

TIMMY Z. said...

I think that both Cameron and Emma could be right. If you had someone pushing the car, than the car would never stop moving until the person stopped pushing it, and the unseen forces would stop the car from the gravity pulling it down, and slowing its speed.

It stopped because it had to slow down some day c: (Cameron)

Austin K said...

I agree with both because theres no friction or push force.

I agree with both because though Cameron's argument is not the cause of the car stoping, yet it still happened.

Gavin R. said...

I agree with emma because newton said that a object in motion stays in motion .

vincent said...

i agree with emma because there is one law of pshcis that say's that their is a force that's called friction that stops the thing that you push

Emma Madore said...

i believe both are right because there both forces

Emma B said...

I agree with emma because friction is an unseen force that stops the car.

I agree with Emma because friction is an unseen force that stops the car.

I agree with both of them because friction is an unseen force.

Macey C. said...

I agree with Emma because friction, an unseen force slows things down until they stop.

A unseen force going the opposite way.

I agree with Emma, because friction is slowing it down.

Emma is correct because of friction it slow the cars momentum

I agree with Cam because he is right.
