If a car is traveling at a constant speed of say, 60MPH, is the acceleration of the car 0, or is it equal to the drag and rolling resistance it's facing?
What do you think and why? What is the definition of acceleration?BoredButCurious said:If a car is traveling at a constant speed of say, 60MPH, is the acceleration of the car 0, or is it equal to the drag and rolling resistance it's facing?

But if we do consider them, then they are always opposing the motion of the car. To keep the velocity of the car constant, the engine has to be kept running, else resistive forces slow u down to rest.
So, a force is applied by the engine just to overcome the resistive forces to keep the car moving with constant velocity.
I hope you understood :-)
