13. A student was asked to set up an experiment to determine
how the angle of a ramp affects the amount of force needed to move
a 1 kg object. Which of the following data tables would be most
appropriate for collecting the data?
Slide 16
14. A moving service is delivering boxes to a warehouse. The
workers used 15.3 N of force to move a box 17 meters across the
floor. Calculate the work being done on the box. Record your answer
and fill in the bubbles on your answer document. Be sure to use the
correct place value.
Slide 17
15. A student was asked to set up an experiment to determine
how the angle of a ramp affects the amount of force needed to move
a 1 kg object. The data for the experiment follows. When the ramp
was set at 90 degrees, it took 10 N of force to move the 1 kg
object. When the ramp was set at 60 degrees, it took 8.6 N of force
to move the 1 kg object. When the ramp was set at 30 degrees, it
took 5 N of force to move the 1 kg object. What conclusion can be
made from the above data?
