what is friction and momentum?
Answers
Answer:
Friction is the resistance to motion of one object moving relative to another
Specific examples of sliding friction include: Rubbing both hands together to create heat. A sled sliding across snow or ice.
Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces.
Calculate the force of friction using the formula: F = μN. Where N is the normal force and μ is the friction coefficient for your materials and whether they're stationary or moving. The normal force is equal to the weight of the object, so this can also be written: F = μmg.
Causes of Friction. Friction is a force that resists the relative motion between two objects or materials. The causes of this resistive force are molecular adhesion, surface roughness, and deformations. Adhesion is the molecular force resulting when two materials are brought into close contact with each other.
please mark me the brainiest...
I have given you all the points about friction....plzzz
Answer:
Friction: Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
Momentum: In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction in three-dimensional space.
