What are measurement: They are tools used in science , physics forgetting exact measurements of and object e.g some of them are vernier calliper meter rules ,micormeter screew guages, thermometer voltmeter, ammeter, measuring cylinder etc.
Instrument for measuring Mass are :
1. Lever balance: it is used to measure mass it units is in kilograms.
2. Chemical / beam balance: it is used in measuring unknown mass.
Instrument for measuring weigh.
1. Spring balance : it is used to measure weight of an object. Weight is measured in Newton .
Instrument for measuring of time
Time is the duration of an event band it is measured in second. Time is measured in second.
_ ticker tape time : it is used to measure short interval of time accurately. It vibrates 50 time's in 1 second and paper tape is used in calculating the distance between vthe dots.
_ stop watch clock: it is an instrument used either in laboratory or field during sporing activity.
_ sand clock : it is used to measure time per hour .
_ simple pendulum: it is used in the laboratory to measure time.
_ heart beat : it is a natural way of counting.
Measurement of distance / instrument .
1. Meter rules.
2. Micrometer screw guages
3. Venirail calliper.
