What is the relationship between pressure, force, and area in physics?
What is the formula to calculate pressure in physics?
A. P = F/A
B. P = A/F
C. P = F * A
What units are commonly used to measure pressure?
A. pounds
B. inches squared
C. pounds per square inch (psi)
Answer:
The formula to calculate pressure in physics is P = F/A. The units commonly used to measure pressure are pounds per square inch (psi).
Explanation: Pressure in physics is defined as the force applied perpendicular to the surface of an object per unit area. The formula to calculate pressure is P = F/A, where P is the pressure, F is the force applied, and A is the area over which the force is distributed.
For example, if a force of 100 pounds is applied over an area of 10 square inches, the pressure can be calculated as follows:
P = F/A
P = 100 lb / 10 in²
P = 10 psi
Therefore, the pressure exerted in this example is 10 pounds per square inch (psi), which indicates the amount of force distributed over a unit area.
