Fluid Mechanics
-
Aerodynamics
Related to the flow of air around a projectile, which can influence the speed and direction of the object
Hydrodynamics
Related to the flow of water around a projectile, which can influence the speed and direction of the object.
Air Resistance
It is a friction force, which occurs when air passes over the surface of objects . Drag force is a force acting opposite to the relative motion of any object moving with respect to surrounding fluid
-
Streamlining
In activities where maximum speed is the aim, the drag must be minimised and this is achieved through streamlining
Bernoulli Effect
As Velocity of the fluid increases, the pressure extended by that fluid decreases. This leads to turbulence behind the object
Magnus Effect
BackSpin
Due to the air resistance formed at the bottom of the ball,the air is slowed down causing an area of high pressure below the ball
Side Spin
In football, players use the Magnus effect to curve the flight path of the ball. The kicker places a side spin on the curling ball, curving it around the wall of the defensive players in goal.
Top Spin
Due to the air resistance formed at the top of the ball, the air is slowed down causing an area of high pressure above the ball
