Which force needs to touch something to have an effect?
The force of friction needs to touch an object to have an effect. Friction occurs when two surfaces are in contact and one surface resists the motion of the other surface. It is this resistance that allows friction to have an effect on objects in contact.
Does surface area have an effect on friction?
Yes, surface area can have an effect on friction. In general, larger surface areas in contact can increase friction due to the increased contact between surfaces. However, other factors such as the material properties of the surfaces and the force pressing them together also play a role in determining the overall friction force.
What is the effect of kinetic friction on a block and pulley system when determining the overall efficiency of the system?
Kinetic friction in a block and pulley system reduces the efficiency by converting some of the mechanical energy into heat. This results in a decrease in the overall efficiency of the system as some of the input energy is lost due to friction.
What is the name for forces where things have to be touching to have an effect?
The name for forces that require objects to be in contact to have an effect is contact forces. Examples include friction, tension, and normal force.
What can you conclude about the effect of friction in the pulley on the value of K?
Friction in the pulley will decrease the efficiency of the system, causing an increase in the value of K. This is because some of the input energy is lost to overcoming friction, resulting in a higher value of the kinetic friction coefficient.
What is the effect of decreasing the surface area of the block in contact with the table on the coefficient of kinetic friction?
Decreasing the surface area in contact with the table will increase the pressure at that contact point. This can lead to an increase in the coefficient of kinetic friction, as the roughness at the microscopic level can become more significant.
What will be the effect on friction when contact points are reduced?
No effect

What effect does friction have on a moving body?
Friction converts kinetic energy into heat. The result is that the moving body slows down.
What are the different ways the lassen or minimize the effect of friction?
By reducing the contact surface area of the object and by applying the lubricant between the two contact surfaces lassens or minimizes the effect of friction.

What can be done to minimize the effect of friction?
To minimize the effect of friction, you can use lubricants between surfaces, choose materials with lower friction coefficients, reduce the contact area between surfaces, and ensure proper surface smoothness to reduce frictional resistance.
What is the plowing effect for friction?
The plowing effect in friction refers to the process in which asperities on the surfaces of two materials interlock and displace material from one surface to the other. This can increase the contact area and lead to higher friction levels between the two surfaces.
Why a cooler is more effect on a hot and dry day?
Sliding friction is when two objects slide across from one another. An example is sliding a book across a desk. It is also known as Kinetic friction.
