Newtons first law of motion --Inertia
2006-09-04 16:00:02 · 5 answers · asked by Peter T 1 in Science & Mathematics ➔ Physics
If the body moves it resists both to be moved faster and to be slowed down. When at rest it wants to remain at rest. This is what the concept of inertia is all about.
When you push a cart you are trying to overcome its inertia by applying force. When you are stopping it again you are applying force to overcome inertia. All of these actions are consistence with the First Law of Newton.
Bottom line: A force must be applied to an object to change its velocity.

Uh, I'm not sure if I can even read this. But in any case, Newtons first law is: An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. So if you stop it (which is what I think you typed) then that sounds ok. You really should rephrase this if you want help.

Hi The force required to move it is exactly opposite to the force required to stop it (including friction, etc.).

No.
What force act on the cart to stop it?
That's the answer to your question.
Hint, it starts with an "F", and creates heat.

No, friction losses caused by gravity in the form of heat causes it to stop.
