force= pressure*area
Pressure equals force/area so from this you can get area equals force/pressure. plug in your numbers and get an area of 3. I'll let you work out the units
Pressure. It is measured as a given force applied over a given area.
An electric field surrounds the charge and exerts force on other charges.
Force = 450N Area Of Contact = 5m * 4m = 20m2 Pressure = Thrust /Area = 450/20 N/m2 = 22.5 PA = 22.5 N/m2
Force exerts pressure. For example: At the surface of the Earth the column of air in the atmosphere above an area has a mass that exerts a force (due to gravity) on that surface area.
That's the definition of the 'pressure' which the force exerts on the surface.
force= pressure*area
Pressure equals force/area so from this you can get area equals force/pressure. plug in your numbers and get an area of 3. I'll let you work out the units
yes, force divided by area is pressure; its units are pounds per square inch, or newtons per square meter, for example. I you pull on an object with force over an area it is called stress
Pressure. It is measured as a given force applied over a given area.
An electric field surrounds the charge and exerts force on other charges.
P = F/A, so Area = Force/Pressure
The Amount Of Force
Force = 450N Area Of Contact = 5m * 4m = 20m2 Pressure = Thrust /Area = 450/20 N/m2 = 22.5 PA = 22.5 N/m2
It is if a brick rests on a table the force with which the brick pushes on the table is its weight. The pressure it exerts on the contact area depends on the brick's orientation. If the contact area between brick and table is larger, the brick exerts less pressure on the contact area.
on tiptoe, because the force acts over less area
