Friction can be unhelpful in situations where you want to minimize energy loss, such as in machinery where friction causes wear and tear on moving parts, reducing efficiency. Additionally, in sports like speed skating or car racing, reducing friction can help increase speed and performance.
Friction can be reduced by using lubricants like oil or grease on surfaces. To increase friction, surfaces can be roughened or materials with higher coefficients of friction can be used. Adjusting the weight or pressure between the surfaces can also increase friction.
You can increase friction on a moving object by either increasing the weight pressing the surfaces together, roughening the surfaces in contact, or increasing the coefficient of friction by introducing a material with higher friction properties between the surfaces.
To reduce friction, you can use lubricants to create a smooth surface between objects in contact. To increase friction, you can increase the force pushing the objects together or use materials with rough surfaces that grip each other more firmly.
Decrease friction .
INCREASE
Yes, as you increase the force exerted by pushing the crate, friction between the crate and the surface will also increase. This is because friction is directly proportional to the normal force between the surfaces and the coefficient of friction. More force results in a greater normal force, leading to increased friction.
Friction can increase as the contact area between two surfaces increases, or if the surfaces are rougher or stickier. Additionally, an increase in force pressing the surfaces together can also increase friction.
Friction between two surfaces can increase due to an increase in the roughness of the surfaces or an increase in the normal force pressing the surfaces together. Additionally, an increase in the surface area of contact between the surfaces can also lead to an increase in friction.
Wax, due to it filling the pores that cause friction will reduce friction.
