What else can I help you with?
A crate remains at rest on a factory floor while you push on it with a horizontal force F How big is the friction force exerted on the crate by the floor?
The friction force exerted on the crate by the floor is equal in magnitude but opposite in direction to the pushing force you apply to the crate. If the crate is not moving, the friction force is static friction, and it adjusts its magnitude to exactly match the applied force to keep the crate at rest.
What property of matter causes an object to have inertia of rest?
The property of matter that causes an object to have inertia of rest is its mass. Mass is a measure of the amount of matter in an object and determines how difficult it is to change the object's state of rest or motion. Objects with more mass have greater inertia of rest.
Why is it 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
Why is it more difficult to slide a crate starting from rest than it is to keep moving once it is sliding?
It is more difficult to slide a crate starting from rest because static friction exists between the crate and the surface, requiring a greater force to overcome. Once the crate is already sliding, kinetic friction is less than static friction, making it easier to keep moving with a lower force.
What is the net for of a box weighing 40N that rests on the floor?
The net force on the box is 0N since it is at rest on the floor. The gravitational force pulling it downwards (weight) is balanced by the normal force exerted by the floor in the upward direction.
Why is it more difficult to push a car from rest?
An object at rest tends to stay at rest.
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.
How could a unbalance force work on a chair at rest on the floor to make it slide across the room?
you can push is across
Can you do push ups the day after you lift weights?
Well, you CAN, but you should rest for about a minute before doing them. If you feel strain you can't handle when doing about 5 push-ups, just to test to see if you can do more, then you shouldn't do push-ups. If you feel strain any time during push-ups, you should stop and rest, then try doing more.
Will doing Push ups for two hours get me a big chest?
You would not be able to do push ups for two hours, and if you were you would lose form and thus eliminate any possible benefit from doing those push-ups. If you would like to grow a bigger chest your best bet would be do the following: Get into the standard push up position, lower yourself (2 seconds down) and push yourself off the floor as quickly as possible. Repeat as many times as you can until you lose form (until you cannot do the push up properly anymore). That's one set, do as many sets as you can until you cannot do another push up correctly. Don't rest more than 3 minutes between sets. I would also suggest performing polymeric push ups (this is where you lower yourself and then push yourself completely off the floor) as they strain your chest muscles more than the normal push ups.
Why does magma move through the volcanoes?
Because nothing can be still and if more magma forms it has to push the rest away
What is things rest upon crustal plates?
The continents and the ocean floor rest upon the plates.
How do you push headrest all the way down?
There is button that you push in that is located at the top of each seat at the base of the head rest. You push the button in to make the head rest go up and down.

Why is more difficult to push a stalled car from rest than to keep it in motion once it has started to run?
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 are examples of objects at rest?
a chair on the floor.
How many push ups should a eleven year old boy do?
Try to do 20, then rest for as long as you need and then push yourself to do 25 and then rest and then 30, catch my drift?
