What is the SI unit of pressure?
Pascal
If the force exerted on a surface increases while keeping the area constant, what happens to the pressure?
Increases
How does decreasing the area over which a force is exerted affect the pressure produced?
Increases
If you increase the surface area of the blades of ice skates, what will happen to the pressure they exert on the ice?
Decrease
What term is used to describe a substance that can flow from place to place and take the shape of the container?
Gas
In terms of unit conversion for measuring pressure, what unit is used when area is measured in square centimeters instead of square meters?
Pound per square inch (psi)
Which principle states that a body immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the body?
Archimedes' Principle
Which principle explains why a ship floats on water?
Archimedes’ Principle
What is the formula to calculate pressure?
$\text{Pressure} = \text{Force} \div \text{Area}$
Which of the following units is commonly used to measure pressure?
Pascals
If a person leans on a wall and exerts a force downwards, what is being exerted on the wall?
Pressure
How does Pascal's Principle relate to pressure?
Pascal's Principle defines the relationship between force, area, and pressure.
What is the formula for calculating fluid pressure?
Force divided by area
If the fluid pressure is 1000 N/m^2 and the area is 5 m^2, what is the force exerted by the fluid?
5000 N
Why don't we feel crushed even with great air pressure outside our bodies?
Because air pressure inside and outside our bodies balance each other
What is the unit of measurement typically used for pressure?
Pascal (Pa)
If a fluid exerts a force of 500 N over an area of 2 m^2, what is the fluid pressure?
$250 , \text{N/m}^2$
How does air pressure act on a flat surface under normal conditions?
Equally in all directions
Test your knowledge on topics like fluid and pressure, pressure at a point in a fluid at rest, Pascal’s Principle, Archimedes’ Principle, and measurement of pressure. Explore concepts of solids being three-dimensional objects with fixed shapes and fluids being substances that can flow.
