The resulting force is called the net force when more than one force is applied to a single element. The resultant force is equal to the difference in the applied forces when two separate forces are applied in opposite directions. Pressure may not affect the velocity of a fluid, but force can change the velocity.
Whereas Force is defined as the action of pushing and pulling, which results in a change in motion and direction. Force is defined as the act of pushing and shooting, which translates into a change of movement and direction. And the force acting on an object in a direction perpendicular to the surface of the object is known by the name of pressure. The pressure is distributed across a certain region. Pascal, or Newton per square foot, is the SI unit for pressure.
Additional units, like pounds per square inch and bar, are also available. Skip to content In our daily life, we can easily find many phenomena connected to pressure. It is a response to something. It operates in a perpendicular direction to its surface.
Force is a type of push or pulls that occurs when two bodies interact and cause an item to accelerate. F is the magnitude of the external force, and. A is the surface area of the surface in contact. Unlike force, the pressure is a scalar quantity, and it has only magnitude. The vector of force acting normal to the surface is the vector element of pressure.
Basis For Comparison. Force is a kind of push or pull, resulting from the interaction of two bodies, that can cause the object to accelerate.
Pressure is force extended over ab area, acted upon something, in the direction perpendicular to its surface. Standard unit. Newton, represented by symbol N. Vector Quantity. Scalar Quantity. Applied to. Faces, Edges and Vertices. Can be changed.
Or if the force in each direction is equal, then the object comes to a halt. Alternatively, the motion will be in the resultant direction. This can be explained by giving the example of a man sitting in a chair. Thus a person remains in the chair with zero resultant motion.
Force is represented by magnitude and direction. It is a vector quantity. The great physician Isaac Newton also described force in his first law of motion. According to this, in order to change the direction of the motion of an object, a force has to be applied on the body. Pressure can be explained as force applied on a unit area. When the force is applied over a large area, then the pressure developed is lower as compared to that developed on a smaller area.
Pressure is a scalar quantity as it is not dependent upon the direction; it is only dependent upon magnitude. Pressure does not change the velocity of the object. Force is vector quantity, that is, it depends upon the magnitude of an object and its direction both; whereas pressure depends only upon magnitude. It is a scalar quantity.
