5 Questions
Explain what thrust is and how it is related to the weight of a body placed on a surface.
Thrust is the force acting normally on a surface. The thrust exerted by a body placed on a surface is equal to its weight.
What is the SI unit of thrust and how is it related to the CGS unit of thrust?
The SI unit of thrust is newton (N) and the CGS unit of thrust is dyne, where 1 N = 10 dyne.
Define pressure and explain how the effect of thrust on a surface depends on the area of the surface.
Pressure is the effect of thrust on a surface. The effect of thrust is less on a large area, while it is more on a small area.
What is the gravitational unit of thrust in the MKS system and the CGS system?
The gravitational unit of thrust in the MKS system is kgf and in the CGS system is gf. They are related as: 1kgf = 9.8 N and 1gf = 980 dyne.
Is thrust a scalar or vector quantity?
Thrust is a vector quantity.
