Why it is not wise to reduce friction always?
Well if you did not have friction you would fall over when you walked. Just think of what it is like trying to walk in ice (which has very low friction).
Can we walk without friction?
To walk without friction is like trying to walk on ice, or over a pool of oil. We need the rear foot to be firmly fixed in order to step forward and take a step without slipping.
How does friction help you walk?
It gives you grip on the ground. Without it perhaps it would be like ice?
If a force is required to pull a 20 kg box across a carpeted floor what is typically true about another force required to pull the box across the ice at a rink?
Pulling a box across ice requires less force than pushing the same box across carpet. This is due to the amount of friction between the carpet and box and the lack of friction between the ice and the box.
How does a Zamboni drive on ice without Friction?
Actually, without friction, the Zamboni would not go anywhere. Ice just reduces friction. There are microscopic pores in the ice, so when the Zamboni is on top of it, the rubber tires press into the holes, so the vehicle gets a good grip. This makes it possible for the Zamboni to move across the ice.
Why is friction impotant when you walk?
If there were no friction between your soles and the pavement, you would be unable to apply the force needed to walk forwards. Think how difficult it is to walk on ice where the friction is low.
Why is it difficult to walk on ice?
Because it's slippy and you would just fall over
WhyIt is not easy to walk on ice sheets?
It is not easy to walk on ice sheets because there is very little amount of friction between your shoes and the ice sheet. Whee there is not enough friction between your shoe and the ice sheet, you will slip very easily.
What game requires little or no friction?
Curling. A kettle is slid across the ice. Team members brush the ice in front of the kettle to minimize friction.
Why do you slip when walk on ice?
Because the friction is less between the two things.
Do moose like to walk on ice?
They slid across.
What are somethings with little friction?
Ice and marble floor have little friction and results in objects slidding as they go across the surface.
What would be easier to push across the desk rubber or ice?
Ice, because it has lower friction than rubber.
How is friction usefull for us?
It holds things in place - try taking a walk on ice.
