Estimated error in recording a data

The measurement with a caliper has a ______________

Uncertainty is also called _______

Used in a context of measurement

Refers to how close it is likely to be the true value, by writing the number and symbol

Also called as r"epeatability' refers to the closeness of two or more measurement to each other

Precision is also called as

Are statictics fluctuations in the measured data due to the precision limitations of the measurement device.

Errors are reproducible inaccuracies that are consistently in the same direction

They comprise all digits that are known with certainly plus the first digit that is uncertain. The position of the decimal point is relevant

The single zero conventionally placed to the left of a decimal points in such an expression in never significant It is used to locate the decimal points

How many significant 14657.3

1.00006017

0.007347

The answer must contain the same number of decimal places as the term with the least number of decimal

The answer must contain the same number of significant figures as the term with the least number of significant figures

If the figures to be dropped is five or greater than 5, increase by one the value of the last figure to be retained

Method of writing or expressing very large or very small numbers into its exponential form

Form of Scientific notation

Number greater than or equal to one but less than ten

Number of times the decimal points is koved. It can be a positive of negative

An object that is thrown in a curve oath with the effects of gravitational field invoves motion in two dimensions

Object that is thrown called

Path is called

A physical quantities with magnitude (size) only

Physical quantity with a magnitude and direction

Examples of scalar quantities

Examples of Vector

A change in position, which has both magnitude and direction.
