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.

Kinetic Friction replaces Static Friction when an object is in motion.
NO friction
Friction can be both a friend and a foe. It is necessary for everyday tasks such as walking and driving, but it can also cause wear and tear on surfaces and materials. Properly managing friction is essential for optimizing performance and reducing unwanted effects.
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 can be both a friend and a foe. It allows us to walk, hold things, and even write due to the grip it provides. However, friction also causes wear and tear in machinery and can slow down motion, which may not always be desirable.
Friction can be both a friend and a foe. It is necessary for many everyday activities like walking, writing, and driving, but it can also cause wear and tear on surfaces and machinery. Strike a balance between needing friction for traction and control, while minimizing it to reduce energy loss and damage.
Friction can be considered a friend because it allows us to walk, drive cars, and hold objects. It provides the necessary grip and traction for various activities. However, friction can also be seen as a foe because it can slow us down, cause wear and tear on machinery, and reduce energy efficiency.
