Physics for IGCSE & O level - Forces And Pressure (Section 6 - No. 32)
If the force acting on an object is doubled, while the area over which the force is applied is also doubled, what happens to the pressure?
Pressure doubles.
Pressure halves.
Pressure remains the same.
Pressure quadruples.
설명
If both force and area are doubled, the pressure remains unchanged because the ratio stays the same.
