fluid mechanics

Question 1

fluid mechanic consist of

Answer 1

water and air

Question 2

air resistance definiton

Answer 2

force acting opposite to the motion of body through air

Question 3

drag definition

Answer 3

force acting opposite to the motion of the body through a fluid

Question 4

factors that impact magnitude of air resistance and drag

Answer 4

velocity 
mass
frontal cross sectional area 
streamlining and shape 
surface characteristics

Question 5

velocity

Answer 5

the greater the velocity the greater the air resistance or drag

Question 6

mass

Answer 6

the greater the mass the less its motion is changed by air resistance and drag

Question 7

frontal cross sectional area

Answer 7

area of the body that hits the water first

the smaller the area is the less fluid friction

Question 8

streamlining and shape

Answer 8

minimises fluid friction which reduces turbulence and smooths the air or water flow around a body

Question 9

surface characteristics

Answer 9

this is the smoothness of the surface of the body

Smooth surface creates less air resistance and drag
