What is the formula for calculating pressure?
Pressure = Force/Volume
Pressure = Force/Area
Pressure = Mass/Area
Pressure = Mass/Volume
Answer explanation
The formula for calculating pressure is Pressure = Force/Area. Pressure is defined as force per unit area, so the correct formula is Pressure = Force/Area.

What are the units of pressure?
N/m
N/m²
N/m³
N/m⁴
Answer explanation
The correct units of pressure are N/m², which represents Newtons per square meter. Pressure is defined as force per unit area, hence the unit N/m².

To work out the pressure acting on a surface, we need to measure the __________ it acts upon.
volume
area
height
distance
Answer explanation
To work out the pressure acting on a surface, we need to measure the area it acts upon. Pressure is force per unit area, so the area is crucial in calculating pressure.

Which of the following is NOT needed to calculate pressure?
Force
Area
Volume
None of the above
Answer explanation
Volume is NOT needed to calculate pressure. Pressure is calculated using force and area, not volume.

If the force acting on a surface increases, what happens to the pressure if the area remains constant?
Pressure decreases
Pressure remains the same
Pressure increases
Pressure becomes zero
Answer explanation
If the force acting on a surface increases while the area remains constant, the pressure will increase. Pressure is directly proportional to force when area is constant (P = F/A).
