Question

1.what is friction?
2.what is meant by streamlined shape.?
​

Answer 1

Answer:

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.

A streamlined body is a shape that lowers the friction drag between a fluid, like air and water, and an object moving through that fluid. ... It occurs when the fluid closest to the object sticks to its surface, exerting a force that opposes the object's motion

Answer 2

Answer:

ans 1

friction force resist for motion.

Explanation:

ans 2

streamlined body is a shape that decreases the friction drag between a fluid, such as air and water, and an object that passes through that fluid. Drag is the force which reduces the speed of the motion. Related Questions & Answers.
