Question

Explain the method to measure length,mass,time.

Answer 1

length means distance : speed× time
mass: force /acceleration
time : distance / speed

Answer 2

Length can be measured by a linear scale rod. The scale is kept with any mark matching the starting edge of object. We will get a mark at the ending point of object.
Final mark-Initial mark= the length of object .


Mass can be measured by a common balance where weights are placed in one pan and the required object in another and when the support comes to an equilibrium, the Mass is known.


Time can be measured by a stop watch. The button needs to be pressed before the starting if event and again as the event ends. For more accurate measurements, instruments like chronometer can be used.
