CHAPTER 10
FORCE, DISTANCE, AND WORK
1. What magnitude of force acts on the object when it has been moved 4.0 m?
_______________________its = 0 ________________________________
2. How far has the object been moved when the force on it is 200.0 N?
__________0.8 * 200 = 160___________________________
3. Explain the shape of the line on the graph.
More active sites are available from substrate molecules, so more active sites are
added, which increases the rate._________________________________________________

4. Which formula is used to calculate work when a constant force is exerted on an object?
________ work is the newton meter or joule (J)________________________________
5. How much work is done in moving the object 4.0 m from the source to 6.0 m from the
source?
6.0 – 4.0 = 2.0
6. Look at the information on the graph about the object as it is moved 6.0 m from its source
to 10.0 m from its source. How much work is done in moving the object?
150 N
7. How much work is done in moving the object the 10.0-m distance shown on the graph?
250 * 10 = 2500
 Write work, energy, or power beside each unit to identify the quantity that it measures.
 Some quantities are measured by more than one unit. Some units are used for more than
one quantity.

 Moving ocean water exerts a force of 375 N on a boat, causing the boat to move a distance
of 34.7 m in 8.34 s. What power does the boat produce?
Work =f x d
Work = 375 x 34.7 = 13,012.5 j
Pawer = work / time = 13,012.5 / 8.34 = 1560 .252 W/1000 =1.56
D=34.7
F=375
T=8.345
 Identify the equation you would use to calculate power if you know the following quantities.
work and time force
distance, and time
P=W/t
P = Fd/t =m*a*d
time and change in energy
force and velocity
P=E / t p1-56 = 39871
W = Fd coc 0 =6+9=134
 Murimi pushes a 20-kg mass 10 m across a floor with a horizontal force of 80N.Calculate
the amount of work done by Murimi on the mass.
W = fd
W= 80n×10m=8x10\2h
