Work Calculation Worksheet
Solve the following problems. Show all of your work and use the proper units. Remember: Work = Force x Distance
Teacher Page (Student Page below)
4. A referee holds up a 0.5 kg flag for one minute to signal
1. A car’s brakes exert an average stopping force of 5000 N
the end of the period of play.
over a distance of 22 m.
No work is done.
Work = Force x distance
W = 5000 N x 22 m
W = 110000 J
2. Rocket thrusts overcome a gravitational force of
7,962,000 N to move a rocket 10,000 m. (Bonus – Can
you express the answer to this question in to scientific
notation?)
Work = Force x distance
W = 7962000 N x 10000 m
W = 79620000000J
BONUS – 7.962 x 1010 J
3. A bodybuilder lifts a 75 kg barbell 2 m onto a bench.
F = m x a [F= 75 kg x 9.8 m/s2
Work = Force x distance
W = 735 N x 2 m
W = 1470 J
F = 735 N]
5. Name the unit to measure each of the following in the
formula W = F x d.
a. Distance  meters
b. Force  Newtons
c. Work  Joules
