Friction slows something down, so you'll need it when you drive the car (the brakes apply friction to the tires and you stop) and when you hold onto something (your hands apply friction to a credit card, thus enabling you to hold it), among others.
You don't need it in some machinery (lubricants and bearings), among others.
What else can I help you with?
Is friction necessary for motion?
No. Friction is just necessary for controlling motion.
Can you not walk without friction?
No, walking without friction is not possible. Friction is necessary between the foot and the ground to generate the necessary traction for walking and to prevent slipping.
What is a situation where friction is necessary?
Friction is necessary when walking to prevent slipping, while driving a car to maintain traction on the road, and when writing with a pen or pencil to create legible marks on paper.
Can we drink from a glass without friction?
No, it is not possible to drink from a glass without friction. Friction is necessary to hold the liquid inside the glass and to help lift and drink from it without spilling.
What part of a moving car experiences the most friction?
The tires of a moving car experience the most friction with the road. This friction is necessary for the car to accelerate, decelerate, and make turns.
Is friction necessary for motion?
No. Friction is just necessary for controlling motion.
Can you not walk without friction?
No, walking without friction is not possible. Friction is necessary between the foot and the ground to generate the necessary traction for walking and to prevent slipping.
What parts of a bicycle is friction necessary and what parts are not necessary?
The bearings don't need friction, but everything else does. It there wasn't any friction it'd be impossible to bolt anything together.
How are friction and force related?
friction increases the amount of force necessary to do work
In what ways can friction be helpful?
Friction is necessary for wheels to rotate and nails to keep in walls.
Why is friction called a necessary evil?
Friction is necessary : If there is no friction between any two surfaces in contact, then the present day civilization will be no more- as we cannot even walk properly on the earth. There will be no fabrics and garments, no construction of buildings and no furniture, even no cooking and no vehicles. So friction is necessary. But too much friction causes a heavy loss of energy, wear and tear of machinery. Thus, the efficiency of machines will decrease tremendously. So, it is rightly said that friction is a necessary evil.
Does friction play a necessary role in a roller?
It keeps the roller down and creates friction to allow the roller to move.
What is a situation where friction is necessary?
Friction is necessary when walking to prevent slipping, while driving a car to maintain traction on the road, and when writing with a pen or pencil to create legible marks on paper.
How is friction good and bad?
Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
Does a pulley use friction?
No, a pulley does not use friction. Pulleys are simple machines that use a wheel and axle to redirect the force applied to them. Friction is not necessary for a pulley to work properly.
Can we drink from a glass without friction?
No, it is not possible to drink from a glass without friction. Friction is necessary to hold the liquid inside the glass and to help lift and drink from it without spilling.
What part of a moving car experiences the most friction?
