Measurement of Time and Motion — Question 3
Back to all questions 3
Question I once watched a part of marathon on a straight road stretch. I noticed that some people seemed to be running at the same speed during that distance while some people would speed up or slow down. How were their motion different? (Page 116)
People who run at. the same speed have uniform motion, but those who speed up or slow down have non-uniform motion.
