Which of the following is Correct about Thrust?
It is the total force acting perpendicular to the surface.
SI unit is Pascal.
Is a type of pressure.

Which sentence is the MOST RIGHT fit for this image?
Flat shoes are better than heels.
Pressure distribution is less for flat shoes.
In muddy area, it's not a good idea to wear heels.
Less the area, less is the pressure. So heels create less pressure.
