Grade 8 Science – Pressure Worksheet
Instructions: Using the following formula P = F/A, answer the below word
problems. Be sure to show all work and write all units.
1. Calculate the pressure on a man’s foot when a woman who
weighs 520 N steps on his foot with her heel which has an area
of 0.001 m2 with all of her weight.
2. Calculate the pressure exerted on the floor when an elephant
who weighs 2400 N stands on one foot which has an area of 0.4
m2.
3. Calculate the pressure exerted on the heel of a boy’s foot if the
boy weighs 320 N and he lands on one heel which has an area of
0.16 m2.
4. How much must a woman weigh (force) if the pressure she
exerts while standing on one foot has an area of 0.6 m2 exerts a
pressure of 16 Pa?
5. What is the area of a car that touches the road if the car’s weight
on that tire is 3072 N and the pressure exerted on the road is 48
Pa?
6. Calculate the pressure exerted on an elevator floor which has an
area of 6 m2, if 20 people whose combined force is 1500 N are
standing on it.
7. How much pressure is exerted on a science lab floor if the lab
desk has an area of 1.08 m2 and a force of 12 000 N
8. How much pressure will be exerted on a diver’s body which has
an area of 10 m2, if the water column above him weighs 120 000
N?
