Systematic errors follow a pattern (instrumental

Systematic errors follow a pattern (instrumental error, personal error, environmental error) and can be reduced by calibration and proper technique. R

Significant figures represent the precision

Significant figures represent the precision of a measurement. Rules include: all non-zero digits are significant, zeros between non-zero digits are si

Every physical quantity has dimensions expressed

Every physical quantity has dimensions expressed as powers of fundamental quantities [M^a L^b T^c]. Dimensional equations help check correctness of fo
