Why it is difficult to push a stalled car from rest than to keep it in motion once it has started to run?

You have to overcome the inertia to move anything from a standstill
Yes, That's Newton's Law of Motion: An object not in motion will remain not in motion until acted upon by a outside force, and an object in motion will continue to remain in motion until acted upon by an outside force....that's why it will roll a little bit on a level surface after you push it until acted upon by gravity to stop it.
Ammendum. Those are not Sir Issac Newtons exact words, I pulled that from memory but it's something like that. The end meaning the same

∙ 13y agoIt's based on Newton's first law of Motion: a body at rest will stay at rest, until acted upon by an outside force. A vehicle that is stopped is harder to move, because you have to overcome its inclination to remain stationary. Once the vehicle has begun to move, you add your influence to the vehicle's forward momentum, thus making your effort less.
But if you mean "why is it harder to push a stalled car, than push one that has a running engine"; then it is because when the engine is, it is engaging the transmission. Even in the Neutral gear, the internal components of the transmission are moving with the engine. With the engine off, everything is stationary and (with a manual gear box) nothing is being lubricated, so you have to use more effort to overcome the internal friction of the drive-train.

Why is it more difficult to push a stalled car from rest than to keep it in motion one it has started to run?
Newton's law of motion.
Why is it more difficult to push a stalled car from rest to keep it in motion once it has started to run?
Force = mass X acceleration. When you start pushing a stationary 'dead weight' you are making it go faster than it was or accelerating it. Once the car is moving at a steady speed, it is no longer being accelerated. The greater the mass or inertia of an object the more it will resist changes in its motion. (See Newton's Laws of Motion.)

Inertia. When you first start to push the vehicle you need to overcome the inertis of the vehicle and provide it with Kinetic energy. Once the vehicle is moving, i.e has kinetic energy, then to keep a constant speed on a level surface you only need to push to replace the energy lost through friction, drag, and other energy losses
What keeps Earth in motion?
plates keep earth in motion
How do you work out when you conceived?
It's very difficult but, if you have her doggy style and you have good balance, you could curl dumbbells and perform one-arm presses while you keep the motion going.
How do you keep a motion sensor light on?
Just keep moving
What is Perpetual Motion Machine first kind?
A perpetual motion machine of the first kind it what we usually mean by a perpetual motion machine. A device which once started will continue to run and do useful work forever without the need to add energy to keep it going. The laws of physics make such a device impossible.
