What does walking have to do with science?
Friction
Is friction useful when walking down an icy street?
It's useful
How do you use friction daily?
Walking , if there is no friction you wont be able to walk properly . Another important thing is driving . In the absence of friction the car wheels wont be able to rotate probably thus the car will just go in circles.
Why a wheel cannot roll without friction?
Walking would not be impossible, but it would be likened to trying to walk on ice. Friction opposes movement, which can also be translated into traction. The more friction, the more of an opposing force the object will feel. Since ice has no friction, slipping and sliding is a problem to deal with. But since the majority of ground material on Earth has some type of friction, the opposing force that it provides also allows the feet to remain firmly planted on the ground rather than slipping out from underneath.
Describe 3 examples where low friction is not useful?
Friction is very useful but it has its own disadvantages. Friction causes wear and tear. Friction spoils the soles of our shoes. friction reduces speed This is all wrong some not useful types of friction are are when airplanes fly the friction causes heat that materials that will withstand which are costly.
Why does friction act in the direction of your motion when you are walking?
Because your feet are pushing backwards and therefore the friction opposes in the opposite direction which happens to be the direction in which you are walking.
Give examples of why you need friction?
Walking to move forward, same for anything that moves. If there was no friction it would be like walking on oil.
What 2 sources of friction do you need to overcome when walking?
The backward force on the ground from the person and a reaction force that moves the person forward.
Can you walk on a friction less floor why?
No. There would be no force being applied to the floor by your foot (friction) so there would be no force from the floor in response pushing your foot forward. According to newton's 3rd law. (every action has an equal and opposite reaction)No I can't.. No one can.
What is the song that has two dancers cheek to cheek walking low forward and then alternating and going the opposite direction?
tango
Can you walk friction-less floor?
When you walk it requires a force which is reacted by the floor in opposite direction. With zero friction it is difficult to make any forward progress as no force is reacted, so you cannot walk but will slip.You can try to put foot down always normal to the floor, and you make some progress, but mostly you will be sliding, not walking.
Is walking static friction?
Walking is static friction because you do not drag your feet along the ground.
What two sources of friction do you have to overcome when walking?
Gravity pushing you down on the earth and friction from the ground are the two types of friction you have to overcome when walking.
Is friction an important force of nature?
Yes, because without it, we couldn't walk. Walking is using the friction on the ground to hold our foot in one place as we lunge forward, so if it weren't for friction, then our foot would slip and we wouldn't be able to go anywhere.
What does walking have to do with science?
Friction
What type of friction is important for walking?
Well it is either static friction or rolling friction
What is the relation of friction on walking?
Yeah! There is a big big big relation of friction with our walking , and even one could not walk if the friction is not present......The reason is that , when we walk on earth, it opposes our motion . What happens there , we try to move forward and the earth tries to let us backward . during this a force known as frictional force or friction is produced due to which we walk. Actually , the friction is produced when a body tries to move over an other body. Many work on the earth are only possible due to the presence of friction.....
