Take to pieces of paper and hold them side by side and an inch apart and then blow between them. Will they come closer together, move further away, or stay in the same place?
Take to pieces of paper and hold them side by side and an inch apart and then blow between them. Will they come closer together, move further away, or stay in the same place?
N.B: I tried two times and got a different outcome. Can you explain me the outcome? Am I doing wrong?
We will use Bernoulli's principle in this problem.
According to Bernoulli's principle, when we will increase speed of the moving gas then pressure within the gas will decreases.
In other words we can say that decrease in static pressure will cause decrease in potential energy because according to this principle sum of mechanical energy is constant.
Mechanical energy = Potential Energy + Kinetic Energy
Mathematically we can express this relation as -
Where
m = Mass
v = Speed
Hence, Increase in speed will increase kinetic energy so potential energy will decrease.
We also know that potential energy depends on distance between two objects.
