How friction is useful in pushing a car?
If you are behind a car, about to push it forward from a resting position, you will need to exert a force on the car to accelerate it from resting position. While you are pushing against the car, however, there will be a reaction force pushing back at you. In order to produce a large net force against the car without being pushed backward yourself, you need to increase the friction of your feet against the ground...so that the frictional force between your feet and the ground prevents you from sliding backward. The combinations of the frictional force and your force pushing forward against the car will cause the car to move forward. The frictional force of the car being moved from resting position also has to be overcome, of course.
When blocking in football why does a defending lineman often attempt to get his body under that of his apponent and push upward?
It reduces the force of his weight normal to the ground. This reduces the friction between his feet & the ground; without this frictional force he cannot push himself forward.
Do frictional forces stops a football rolling itself on the ground?
see it is given in the nstse book you are saying that how mad
What force happens when you throw a ball?
The resistance the ground has on the ball causes it to slow down and this force is called friction. Ice has little friction which is why the ball would have rolled further on ice for instance.
What factors determines the strenght of the frictional force between two surfaces?
First the normal force or the force perpendicular to the ground and then the coefficient of friction which has different values based on "type of surface", "wet/dry/lubricated", "object in motion or at rest", etc.
What can you push?
While pushing we actually apply force on the ground which is opposed by frictional force acting on our feet.The ground now applies a normal reaction force on us which we apply on the body to be pushed.
What are the frictional forces while riding a unicycle?
there's friction between saddle and butt, between shoes and pedals, between tire and rim, between tire and ground.

What is an example of favorable?
One of the most important frictional forces to humans is the static frictional force that the ground exerts on a body. Without this force, walking would be impossible, cars would go nowhere.

What is ground fault in the NEC book?
A ground fault is where there is unexpected current on ground. It represents an imbalance between (hot) current supplied and (neutral, or opposing hot) current returned. That imbalance, by Thevanin's current law, must mean there is current on ground.Usually, a ground fault represents a malfunction or short in the load. Sometimes, it represents a cross tie or interchange of ground and neutral. In any case, a ground fault must be corrected, because it represents an unsafe condition, and because the NEC requires such correction.Some times this is a bit tricky to see, since neutral and ground are tied together at the distribution panel and at the service transformer. Since the NEC, however, requires isolation between ground and neutral except at the panel, detecting ground fault is somewhat straightforward, usually measured with a differential current transformer, comparing hot and neutral or opposing hot.I do not have a copy of the NEC in front of me. This is an intellectual answer, but I believe it to be consistent with the NEC's formal definition of a ground fault. Please, anyone with the formal definition, feel free to refine this answer.

How does man walk?
When we walk on the ground our foot pushes the ground backward, and in return, the ground pushes our foot forward. The forward reaction exerted by the ground pushes our foot forward. The forward reaction exerted by the ground on our foot makes us walk forward.
What is 'Terra Firma'?
Terra Firma is the ground, or the firm earth. It represents the ground we stand on unshaken and not moving.
