Friction is important for all sports.
Without it it becomes really hard to accelerate
For example a 100m sprinter.
It would be great for him if there wasnt any air resistance (as long as he can breath).
But he needs friction on the floor to push himself forward.
However friction is less useful in hockey, skiing, and almost all types of boarding(Snowboarding, wakeboarding, kneeboarding,

∙ 8y agoFriction is used to stop things slipping, for instance when you prop a ladder against a wall the thing that stops it from slipping is friction between the top and the wall and between the bottom and the ground. Friction helps us to apply a force effectively. If there were no friction between your shoe and the ground, you couldn't push forwards to walk. Think of how hard it is to walk on a low friction surface like ice. It's the same with car tyres and the road.

Describe three different ways to decrease the force of friction between two surfaces that are moving past each other?
Three ways to decrease the force of friction are- 1.)Polishing 2.)Lubrication 3.)Ball Bearings
What is bad friction in gears?
bad friction is when 2 things rub together .
What are 3 facts about friction?
1) friction thats lows things down is called dynamic friction 2) friction that stops things is called static friction 3) most of friction makes heat ( rubbing hands together )
Explain three ways that coating can improve a surface?
1). Improve the appearance of an old structure 2). Protect the surface from harmful elements 3). Protect surface from aging
What is C60 used for?
C60 is a molecular crystal. It is called buckminsterfullerene. C60 is a allotrope(it means 2 or more forms of the same element in the molecules are arranged in different ways)of carbon atom. The structure of it likes a soccer ball, the carbon atom arranged at 60 vertics of32interconnecting pentagons and hexagons.
Name two ways in which friction can be increased?
Okay 2 ways for the friction to increase is speed and non lubricant
2 ways that friction is helpful?
Car BreaksBike Breaks
2 ways friction can be increased?
Going faster and run fast
What are two ways you can reduce friction in a machine?
A lubricant such as oil and ball bearings are just (2) methods of reducing friction.
Name 2 ways you could increase friction?
you can get old piece of wood
What are two ways that electric charage can be produced?
1. By friction. 2. by magnetism
Name 2 ways that friction is helpful when riding your bike?
Friction lets the drive wheel push you forward, and allows your brakes some bite. Friction make it possible to hold on to the bars. Friction lets you steer.
What are ways to increase friction?
1)increasing the roughness of the surface 2)increasing the mass of the object
What are the ways that can decrease friction?
1) using a lubricant film between moving parts. 2) using low friction materials, such as Teflon.3) reducing surface roughness.
Give the ways of increasing and reducing friction?
By making the surface rough for increasing friction....... use any lubricating material to reduce the friction.. use rollers to decrease the friction force.. make less contact between 2 connecting materials..
What is a sentence you can use for the word Friction?
Friction Is the Force that makes it harder for two things to move against one another. 1) When I rub my hands I make friction. 2) When friction is used , energy is produced.
What friction is used while driving?
1) Friction of the tires on the road 2) Friction in the clutch 3) Friction in the brakes 4) Friction of driver against controls and seat Friction of air also plays a part in resisting motion; this can be used to improve road holding when we deflect it into a down force, hence the spoilers on F1 cars, for example
