Pressure is force acting on a unit area of a surface when force applied on object in a particular area of object exert pressure on it.
A force is called thrust when it acts
normal to the surface
inclined to the surface
parallel to the surface
at any arbitrary direction on the surface
When a force acts vertically downwards or normal to the surface under consideration, it is called thrust.
Thrust is which type of force:
Parallel
Perpendicular
normal
Both b and c
The force which is perpendicular to the surface on which it is acted is called a thrust.
Which Newton's laws describe thrust?
First and second
second and third
only second
first and third
Thrust is a reaction force described quantitatively by Newton's second and third laws. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction on that system.
