Would it be better to increase or decrease friction in swimming?
If you want to swim faster, then decreasing friction would help you with that - Less friction means you glide easer through the water. If you want a more efficient workout then increasing friction would help you with that. If you were to put a track suit on before entering the water you'd have to work a lot harder for each lap in the pool.
Is friction something you want to reduce?
no, actually many inventions or things work on the basis of friction for example a pen it works on the basis of friction.Anything that would once be in motion would never stop.
Would velcro work with no friction?
no
Do you want to reduce friction when you are sitting on a park bench?
Normally you would not want to do so. If there was no friction, you would slip right off the bench onto the ground. You need some friction in order to stay in one place.
What objects work well because of friction?
cars work well with friction because if there was no friction and a car tried to turn it would probably slip and slide and therefore a car works pretty well with friction
What shape has the most friction and why?
You would want to maximize area of contact, and for air friction you would want to maximise the area facing the wind, or direction of motion, Either way the most friction is had from a sheet, provided it can be kept in the right orientation.
How is friction helpful whilst driving a car?
There are many ways that friction is helpful while driving a car. Probably the most obvious one is the frictional force that exists between the tires and the road surface. If there was no friction, the car would not be able to move. The tires would simply spin in place. Various tire compounds will yield a different coefficient of friction dependent on the application (for example, you would want a higher coefficient of friction in racing slicks than you would need for street tires). There are areas of the car where reducing the coefficient of friction based on the specific materials used would be more helpful. For example, you would want as little friction as possible to occur between internal engine components like that between the piston rings and the cylinder wall because you want your engine to be more efficient (the engine doesn't have to work as hard to produce power if it doesn't have to work against it's own internal friction). Hope that helps!
Why do you need friction on animals?
Because without the friction on animals the the neutrons of the atoms would not be able to work properly.
Why would machines work better without friction?
The smaller amount of friction a machine has, the more efficient it becomes.
Is friction will work against force?
Friction will work against force
How can you decrease the friction between your hands and a piece of equipment?
I am not sure if you would want to decrease the friction on your hands, because in the case of using a screwdriver, for example, the friction causes your hand not to slip. However, in a situation where it may be beneficial to reduce friction, anything from sweaty palms to greasy palms would work. (they reduce the frictional coefficient) As an alternative, since frictional force is F = mu * N, you can also reduce F by reducing N (the normal or perpendicular force). In other words, if you want to decrease the friction, don't hold the piece of equipment as tightly.
When might you want to increase friction between two object?
Turning wheels against surfaces would require some amount of friction.
