state two ways of increasing friction between two surfaces
Answers
Answer:
There are two methods of increasing friction: one is by making the surfaces rough and the other by increasing the mass of the object that is moving. For example, the tyres of vehicles have treads (these are the 'designs' that you can see on the tyre surface), which increase the friction between the tyre and the road.
Answer:
These are the 'designs' that you can see on the tire surface.
Explanation:
Step 1: There are two ways to increase friction: one is to make the surfaces rougher, and the other is to add more mass to the moving item. The treads on car tires, for instance, increase the friction between the rubber and the road by creating the "designs" you can see on the tire surface.
The surfaces that come into contact must be made rougher to enhance friction. The energy between the two surfaces in contact can also be increased by applying more pressure. The use of materials that adhere to surfaces raises friction between them as well.
Step 2: Making the surface uneven can increase friction. Friction can be decreased by using lubricants or particles between the surfaces. Instead of using moving friction, ball bearings use rolling friction. Friction is decreased because rolling friction is lower than moving friction.
Even though neither item is moving relative to the other, the frictional force between two surfaces tries to slide one across the other. The net force parallel to the surface plus friction is always equivalent.
These are the 'designs' that you can see on the tire surface.
