Investigating Pressure • SimpliPhys

Each square = 1 cm × 1 cm — Count the squares inside the outline

Choose subject:

Force (N) = mass × 10

500 N

Total area (cm²):

Your calculated pressure (N/cm²):

Select a subject from the dropdown.
Count the number of squares in the footprint grid Check the area of each square.
Enter the area in "Total area" include the fact that there are multiple feet
Calculate pressure: Pressure = Force ÷ Area
Enter your pressure and click "Check Answer"
If correct, click "Add to Results" to save
Try "Custom..." to enter your own mass and foot area

Subject	Mass (kg)	Force (N)	Area (cm²)	Pressure (N/cm²)	Validation	Actions

Force (N) = mass (kg) × 10 (N/kg) gravitational field strength on Earth

Area (cm²) = total area of all feet

Pressure (N/cm²)

Same force on smaller area = higher pressure.
