wat is the difference between force and thrust?

In simple words, force is the push or pull on any object. Thrust is the perpendicular force exerted by any object on the other object.

In physics, a force is any influence that causes an object to undergo a change in speed, a change in direction, or a change in shape. Force can also be described by intuitive concepts such as a push or pull that can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate, or which can cause a flexible object to deform. A force has both magnitude and direction, making it a vector quantity.

Hi,

the difference between force and thrust is not much. Thrust is a kind of force, and the term is usually used with respect to propulsion of a vehicle. 

Hope this helps you

and thrust is the total force exerted by a body on any surface perpendicular to its surface.

its nt corect

force is , u know , force.....

thrust is the force in perpendicular direction............each thrust is a force but each force is nt a thrust...........

rate if u like and ans my ques frm my profile too

 Thrust is Force. Though thrust is force, we use this term in the case of fluids only and we do not use this for solid objects. 
.
If a solid object of mass m is at rest on a surface, and the contact surface area is A. The force acting on that area is mg, the weight of the object. Whatever the shape of the object, the force acting on the area of contact will be the same as the weight of the object.

In the case of liquids, it is different, the force that is acting on the contact area is not termed as force, and instead it is called thrust to differentiate the force acted on by a solid. Whatever is the area of contact the thrust (force) is determined not by the weight of the liquid over it, but it is determined only by the vertical water height (and density) of the liquid.

In the case of solids, the force acting per unit area is called stress and in the case of fluids the thrust acting on unit area is called pressure. 

The pressure at any point inside a liquid on a horizontal surface will be the same, whereas the stress (pressure) at a point on a horizontal surface of a solid will be different at different points.    i tried to clear you everything dont get confused that why i explained you extra thing....thumbs up plz

 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.

force is any influence that causes an object to undergo a change in speed, a change in direction, or a change in shape.

 well,force is an external agency due to which object  undergo a change in speed, a change in direction, or a change in 

dimension.

thrust is a term used for force acting in perpendicular direction.

 Thrust and pressure

 

 

 
Thrust is a total force in a particular direction. The unit of thrust, therefore is the same as that of force : Newtons (N). Pressure is the force or thrust applied per unit area.

   Force (or thrust) 
Pressure (P) =  
 Area

A unit of pressure is Newtons/m2 or N/m2. The unit is also called a Pascal (Pa). There are other units in use also but these are the units in the M.K.S. system.

To appreciate the difference between thrust and pressure, do the following experiment. Take two trays filled with sand and one heavy rectangular block that measures 1 kg. Keep the first block on its side in one tray and the second block on its base in the second tray. You will notice that the first block has sunk deeper in the sand. Although the weights of the two blocks is the same then why does this happen? Since the weights are same, the thrust or the force applied is the same in both the cases. But the area on which this force is acting is different in the two cases. In the first case, the area is smaller hence the pressure is more. In the second case the area on which the force is acting is larger, hence the pressure is less. Thus, we can explain why the first block sinks into the sand more than the second block; in the first case the pressure applied is more. 

We can see several application of pressure in our everyday lives : cutting tool edges are sharper than their heads, a pressure applied on the head is magnified at the edge. The same is true with pin heads or nails, they can be pushed with minimum pressure on the heads.

 1. Thrust and pressure  

 

Thrust is a total force in a particular direction. The unit of thrust, therefore is the same as that of force : Newtons (N). Pressure is the force or thrust applied per unit area.

 Thrust  is the  force that  is acting  normal to a surface.

 

Pressure  is  thrust  acting on unit area.

  Pressure = thrust / area  (or)  Force / area
