How can friction be considered a force?
Friction is caused by force. If you move books across a table (a force) It causes friction. High friction is if the books move slowly, low friction is if the books move smoothly.
What causes increased friction?
Rubbing two things together. Even if you're just sliding across a carpet, that's friction too.
When is low friction useful?
High friction is helpful for traction. For example getting a vehicle moving, making sure it turns on curves, and stopping. Sanding might be another use of high friction. Low friction is helpful for many other things. For example, back to the car, wheels must turn easily, engine parts must turn. Everything runs better and uses less fuel with low friction. Bearings help with lowering the friction. Moving a heavy container from one side of the room to another might be benefited by low friction. You could either slide it... or perhaps pick it up with a low friction handtruck. Ice skating? As we make things move faster, even the friction of air becomes significant. So people choose aerodynamic (or low friction) shapes.
Give an example of two surfaces that would have a low coefficient of friction?
Friction is the static electricity of two things that are rubbed against each other. Ice would have a low coefficient of friction, as things could easily slide across it. This would also make sense for something like marble, which is very smooth.
Why does our eraser get smaller and smaller as we use it?
When you use an eraser to rub something, friction is produced. Friction causes wearing and tearing of things rubbed against a surface. Hope this helps :-)
How do you keep the pressure under a train low?
because if not then you have friction and friction causes massive problems

How do you write a sentence with the word friction in it?
When you rub two things together, it causes friction.
Does friction causes things to slow down?
yes
Can you find things that have low friction?
ice skating
How is friction defined scientifically?
Friction is a force present when things rub against eachother. Friction causes heat energy, and it also causes motion between surfaces to be reduced.
How can friction be considered a force?
Friction is caused by force. If you move books across a table (a force) It causes friction. High friction is if the books move slowly, low friction is if the books move smoothly.
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.
Can low oil cause a car to overheat?
Yes.having low or no oil causes friction in the pistons which will cause car 2overheat.
