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.)

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

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.
Is a force required to keep an odject in motion?
no
Is a force requierd to keep a object in motion?
