Hidden Forces



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

I agree with Charlie because if you give the car one push and not push anymore, its going to stop.

Charlie is correct because there wasn't enough speed to make it continue to move.

gravity or friction is probably stopping the car

Grace L. said...

Charlie because if there is nothing pushing it it will stop

adien is right particals in the air and the friction between the wheels is stoping it

Charlie is right because of two reasons one is the energy is lost in how far it goes and number two is Charlie is awesome

Charlie F. said...

I am right because once you push a car and don't give it enough force to keep going, it will run out of what it's movement was based off of.

Aiden toy said...

I would be an idiot to say that an outside for is stopping the car

charlies right because without enough force the car wont go far.

sofia pothier said...

Charlie is right because if you don't use force it will run out of momentum and stop before hitting something

Both of them are right. They are both right because the energy that was propelling the car ran out and when you input aerodynamics, where/ what the car is driving on, the traction, and the resistance.

Thunder said...

Charlie is right because the car doesn't have enough energy to keep the car going.


it would be both if aerodynamics was part of this.

charlie is right cuz the force ran out

I think its just because it ran out of energy from the push

Anonymous said...

Charlie is right because the original force from the person to the car ran out. I think idk

Aiden is right because the car stopped because of gravity and you can't see gravity.

Big Ev said...

i think the force that was pushing it stop and ran out of motion.

Gracey said...

I think it didn't have enough force to push it but I also believe that even if there was enough force the car could bump into things which would cause it to stop, or the car could change direction either speeding it up or slowing it down.

aiden is right is right because the car stopped because of gravity and you cant see gravity.

the "car" ran out of motion

I agree with Charlie because it stopped by friction
