```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
