Motion and Speed
What unit do we use for speed?
m/s
Which type of forces results in motion?
Unbalanced
Four wrestlers step on a scale for a tournament. Wrestler A weighs in at 170 pounds, wrestler B weighs in at 168 pounds, wrestler C weighs in at 171 pounds, and wrestler D weighs in at 169 pounds. Which of these wrestlers experiences the greatest force due to gravity?
Wrestler C (171 pounds)
What is Newton's First Law of Motion?
Objects in motion stay in motion and objects at rest stay at rest unless an unbalanced force acts up it.
