What else can I help you with?
List the two types of friction and give an example of each?
The two types of friction are static friction and kinetic friction. Static friction occurs when two surfaces are in contact but not moving relative to each other, while kinetic friction occurs when two surfaces are in contact and are moving relative to each other. An example of static friction is pushing a heavy box that is initially at rest, while an example of kinetic friction is dragging that same box once it is in motion.
Give an example of sliding friction?
Sliding your hands together is an example of sliding friction.
What is a harmful and helpful example of friction?
AdvantagesHelps holding objectsCauses objects to come to restdisadvantagesReduces machinery efficiencyOpposes movement of an object
Explain the difference between static friction and kinetic friction. Give an example of each.?
Static friction occurs when two surfaces are not moving relative to each other, while kinetic friction occurs when two surfaces are sliding past each other. An example of static friction is trying to push a heavy box that won't budge, while an example of kinetic friction is the resistance when sliding a book across a table.
When is decreased friction helpful?
Decreased friction is very helpful in working machinery, because friction causes wear and tear.Mainly its very helpful in moving parts. Decreased friction is also helpful in electric cables and wires, as reduced friction reduces energy loss via heat.
The friction between the bristles of your toothbrush and the surfaces of your teeth is an example of?
Helpful Friction.
What is an example of helpful increase in friction?
sandpaper used to smooth wood
4 types of friction and give an example of each?
Rolling Friction, Static Friction, Sliding Friction, & fluid Friction
What would be an example of a helpful decrease in friction?
Deep tread added to snow tires.
When friction is not helpful?
Friction can be helpful and not helpful it is not helpful when you are running because it slows you down hope that'll help!!!! ;)

Where friction is helpful?
Friction is helpful between car tyres and roads for grip. It is also sometimes used for heating as friction generates heat.
Give an example of an unbalanced force causing a change in motion?
friction :)
Give an example of sliding friction?
Sliding your hands together is an example of sliding friction.
Give an example of fluid friction?
A plane moving through air. Air is causing friction, A boat moving through water .Water causes friction.
Give an example of when friction is a hindrance?
Friction can be extremely irritating, for example if you are trying to open a rusted door or slide along a carpeted floor without stopping once.
What is the helpful way friction affects a car?
By using kinetic friction
