Answer to Question #78 in Mechanics | Relativity for Belinda

Question

Can a car move uniformly along a horizontal road with the engine shut off?

Answer 1

Yes, it can. The car can move uniformly along a horizontal road with the engine shut off in the approximation and if we neglect the friction forces on the asphalt, as well as air resistance. In general, due to inhibition this movement can not be uniform under real conditions.
