Friction is caused when objects or substances bump into each other. When you swim you create friction between you and the water which is called Fluid friction. Better yet look it up
Since friction means a contact force, the nature of contact will influence friction force. Smoothness of objects affect the friction force. However, as contact pressure rises, the friction does not rise.
it is very stupid and dumb
Dry friction and fluid friction. Dry friction resists motion of two solid surfaces in contact, while fluid friction describes the friction between layers of liquid that are moving relative to each other.
The two factors on which friction depends are as follows 1. Area of contact 2. Mass of object
The cloth surface area and the air rubs together causing friction or drag which slows the parachute down.
Yes. Roughly speaking, smooth surfaces tend to have less frictional force.
The coefficient of friction is influenced by factors such as the roughness of the surfaces in contact, the materials of the surfaces, and the presence of any lubricants or contaminants.
Factors that influence the magnitude of sliding friction include the nature of the surfaces in contact, the force pressing the surfaces together, surface roughness, and the presence of lubricants. Friction increases with rougher surfaces, higher normal forces, and absence of lubrication.
The friction of an object is affected by the roughness of its surfaces, the amount of force pressing the surfaces together, and the type of materials involved. Factors such as the presence of lubricants, temperature, and speed of movement can also influence friction.
Any glacier moves down a mountain or other slope because of the influence of gravity overcoming the influence of friction.
Some of the factors that influence friction include the lubrication between two surfaces and the surface area of the two materials in contact. Sharper objects like stilettos have more friction on a surface than flat shoes.
Friction helps a car drift by providing the necessary grip between the tires and the road surface. The right balance of friction allows the driver to control the car's slide and maintain control during the drift. Insufficient friction can result in a loss of control, while excessive friction can hinder the car's ability to slide smoothly.
