Activities that require increasing friction can include using sandpaper to roughen a surface or tightening the grip of shoes with a shoelace. Activities that involve decreasing friction can include applying lubricant to machine parts or gliding on ice skates with a thin layer of water on the ice.

What are the activities that require increasing friction?
Activities that require increasing friction include stopping a vehicle, walking on icy surfaces, climbing a steep hill, and using tools or equipment that need a strong grip, like gripping a hammer or a tennis racket.
Why does friction occurs?
Friction is a force which always acts opposite to the force applied on the surface of a body. This opposing force is necessary for many day-to-day activities. Had friction not been there, you wouldn't have been able to walk, write, drive, etc.There are various ways of increasing or decreasing friction. Lubrication, use of ball bearings, use of anti-friction alloys, use of compressed air, etc are some of the ways of decreasing friction.While roughening the surface, drying the surface etc are the ways of increasing friction.Friction occurs because the surface of any object is rough.No surface is completely smooth, they are rough (if not visibly, then microscopically). When they touch each other, the ridges catch on each other, producing heat/friction.because when 2 objects rub together it makes a force that interacts with the other object.
Why sliding friction is important?
Sliding friction is important because it allows us to walk, drive vehicles, and engage in various activities that require friction between surfaces. It helps to prevent slipping and skidding by providing the necessary grip and traction. Sliding friction also plays a crucial role in machinery and industrial processes where controlled friction is needed for proper functioning.
When do you need a little friction?
A little friction can be necessary in situations where you need to slow down or control movement, such as when driving a car or walking on slippery surfaces. It can also be helpful in activities like sports that require traction or grip.
How does surface roughness cause friction?
Surface roughness creates additional contact points between two surfaces, increasing the amount of resistance to motion and leading to higher friction. Asperities on the surfaces interlock and require more force to overcome, resulting in greater frictional forces between the two surfaces. Smoother surfaces have fewer contact points, reducing friction.

What is two reasons for the increasing demand for power are?
The population of the world is increasing and a larger amount of daily activities require electricity (video games, brownsing the web, etc.)

What kind of friction require more force to overcome rolling friction or sliding friction?
Sliding friction requires more force to overcome its friction.

Does an airplane flying require friction?
it doesn't require friction but it requires the air to flow in the right way over the wings to make it rise or lower in the sky
Which type of transfer does not require the presence of matter?
