Pressure is scalar but force is a vector.
Pressure is defined as the force per unit area.
As we multiply area vector by the pressure which is scalar, we get the force vector. This is similar to get momentum vector by multiplying velocity vector by the mass which is scalar.
Unit of force is newton but unit for pressure is N m-2
A force is a push, pull or twist. Any continual force on an object causes that object to accelerate. Pressure is the force over a given area. Pressure is calculated by the formula P = F/a where P=pressure, F=force and a=area over which the force acts. Therefore, the force of gravity, say, on a lady is much smaller than the force of gravity acting on, say, an elephant. However, if the lady is wearing stiletto heels then the force of gravity on her would be the same, but the pressure would be very high as the area of the heels is very small. In other words all the force would be acting over a very small area - sufficient to do a great deal of damage to a floor. On the other hand, the elephant exerts a much bigger force on the floor as it is bigger than the lady, but the pressure would be less as that force would be spread out over a larger area of its four wide feet.
Force is that which changes or tends to change the state of rest or uniform motion of a body along a straight line. Force = mass x acceleration. Its SI unit is newton (N or kg m / s-2).
Pressure is the force acting per unit area on a surface. Pressure = Force / Area. Its SI unit is pascal (Pa or kg m-1 s-2).
The pressure gradient force is not actually a force but the acceleration of air due to pressure difference (a force per unit mass).
is the same
the pressure ;)
there is no difference between high pressure and performance chromatography
As the pressure gradient increases, the wind velocity increases. This is because a larger pressure gradient indicates a greater difference in pressure between two points, leading to a stronger force exerted on the air. This stronger force results in faster wind velocities.
what is the difference between thrust and pressure?
There is a huge difference between tension and pressure in physics. Tension refers to a pulling force and pressure refers to a pushing force.
Pressure deals with the impact on a particular surface while force is the total impact on a particular surface
The upward force is called lift.
by the teacher
pressure is force divided by area
The cause is the pressure difference between the gas pressure in the bottle and the atmospheric pressure.
The pressure gradient force is not actually a force but the acceleration of air due to pressure difference (a force per unit mass).
Pressure = Force/Area
This is called a "bouyant" force. It is due to the difference in water pressure between the top of the object and the bottom of the object. Water pressure increases with depth.
Pressure is the force over an area applied to an object in a direction perpendicular to the surface. Force is a push or pull that can cause an object with mass to accelerate. Force has both magnitude and direction. p = F / A, where:p is the pressure,F is the normal force,A is the area.
Pressure = Force/Area.
