Use Slideshow to click through this page follow
directions to complete the next slide
Step3 Make sure friction is on for first trial
and then do it again with friction off fill in
table on next slide
Step 1 Type 500 Newtons into force box
Step 5 Put Applied force and friction values
into table on next slide calculate your
acceleration and enter that.
Step 2 Pick your object, same as chart on next
slide
Step4 Hit go then hit pause.
