A state of movement A change in position A state of no motion The speed of an object

17. What is the main advantage of standard units?

They are easy to memorize They ensure global uniformity in measurements They require no tools They change for every object

Vernier caliper Measuring tape Stopwatch Ruler

25. What is the basic difference between rest and motion?

Rest means no position change, motion means position change Rest means speed increases, motion means speed decreases Rest means an object is fast, motion means it is slow Rest requires energy, motion does not
