Pressure

Question 1

Name the unit for pressure, and give it’s symbol.

Answer 1

Pascals (Pa) or Newton metres squared (Nm2)

Question 2

Name the unit for area and give it’s symbol.

Answer 2

Metres squared (m2)

Question 3

What is the formula for pressure, given force and area?

Answer 3

P = F / A

Question 4

What is the formula for force, given pressure and area?

Answer 4

P = F / A so F = PA

Question 5

If force decreases what happens to the pressure?

Answer 5

The pressure decreases. Since P = F/A, pressure is proportional to force.

Question 6

What would higher pressure on a person do to footprints if they were walking in sand?

Answer 6

Higher pressure means the footprints will be deeper
