Friction can be considered as a friend or a foe. Friction as a friend: 1.It helps us to hold things. 2.It helps us to move. It helps us to move over wet floor or a muddy track. 3.It helps us to attach many things on the wall surface. 4.The friction between the wheels and the vehicle allows the vehicle to stop, start or change the direction. Friction as a foe: 1.It wastes a large amount of energy as when 2 objects rubs each other, a large amount of heat energy is released.

Case 2: A truck is travelling at a constant speed up a hill with a normal force of 1360N. The Force of the Kinetic friction acting on the truck is 266N. What is the coefficient of kinetic friction between the truck and the road? N = 1360N, Fk = 266N Step 1: Substitute the values in the below Kinetic Friction Coefficient formula: This example will guide you to calculate the Kinetic Friction Coefficient manually.
1. Static2. Sliding3. Rolling4. Air5. Fluid
Kinetic Friction replaces Static Friction when an object is in motion.
NO friction
both friend and foe naw im ko its a friend because you can eat jobby
friction is actually both it just depends on what 2 things are rubbing together.
yes because you can warm your hands by friction when it is cold, but friction can stop you when you are trying to go down a slide.
Friction can be a friend when walking and when driving a car. For example, walking or driving on ice can be very risky due to the lack of friction. Friction can be a foe when it causes more work to have to be done or excess heating. Friction is responsible for our getting blisters on our hands or feet.
Friction is a friend, since without friction we would all be sliding/falling. Cars wouldn't be able to break in time without skidding and colliding with one another. -rene
It allows to walk comfortably. It allows us to grip and catch other object
yes it a foe but without friction in our like we cannot like. when there is no friction we cannot walk or no body can stand on the surface because were there is less friction we cannot stand it will be smooth
friend or foe...no
