Thank you!

Yes, according to Newtons first law I would think it is?

Yes, you are right. The resisting forces won't increase I assume. If the car is still, it means the resisting forces and the driving forces are equal? But then it's the driving force which is decreasing? While the resisting forces are the same. I may be very lost.

Yes, I think those resisting forces is what keeps a car at a constant speed. But then when the driving forces stop, the resisting forces increase, which causes the car to slow down?

An unbalanced force in one direction. I think it is the friction force?

I think that is the net force, that tells me that the car is accelerating.

Homework Statement A car driving at a speed of 60km/h at a horizontal road. The car accelerates to 65km/h, and then the engine gets deactivated. The speed then decreases to 55km/h in a time of 7,2 seconds. The mass of the car is 1450 kg(the car, passenger etc...) Homework Equations What is the...

I'm currently studying physics and mathematics at a high school in Norway, and will continue to study computer science or physics in Germany. I've recently gotten interested in physics, and I want to learn and understand more about it by communicating with others and teaching others, and...
