Answer to Question #236493 in Mechanics | Relativity for esme

Question

describe the changes in the way energy is stored for a petrol car accelerating from rest to a velocity of 80km/h on a level road. assume no energy is lost to the surroundings.

Answer 1

Internal combustion engine within a car tends to convert potential chemical energy in oxygen and gasoline into thermal energy that is further transformed into mechanical energy which accelerates the car from rest to 80 kinetic, ie increase in kinetic energy through causing pressure as well as work performance on pistons.
