SPM Form 4 Physics Chapter 1: 1.4.0 Measurements and Error
http://physics401.one-school.net/2009/01/140-measurements-and-error.html
SPM Form 4 Physics Chapter 1. 140 Measurements and Error. Error is the difference between the actual value of a quantity and the value obtained in measurement. There are 2 main types of error. Systematic errors are errors which tend to shift all measurements in a systematic way so their mean value is displaced. Systematic errors can be compensated if the errors are known. Examples of systematic errors are. Which cause by an incorrect position of the zero point,. Consistently improper use of equipment.

http://physics401.one-school.net/2009/01/121-base-quantities.html
SPM Form 4 Physics Chapter 1. A physical quantity is a quantity that can be measured. A physical quantity can be divided into base quantity and derived quantity. Base quantities are the quantities that are conventionally accepted as functionally independent of one another. It is a quantity that cannot be defined in term of other physical quantity. The base quantities and its units are as in the table below:. Definition of SI Base and Derived Unit. January 3, 2010 at 8:58 PM . Ok ar modul nih. Belajar ph...

SPM Form 4 Physics Chapter 1. 13 Scalar and Vector Quantities. Scalars are quantities which are fully described by a magnitude alone. Magnitude is the numerical value of a quantity. Examples of scalar quantities are distance, speed, mass, volume, temperature, density and energy. Vectors are quantities which are fully described by both a magnitude and a direction. Examples of vector quantities are displacement, velocity, acceleration, force, momentum, and magnetic field. Vectors - An Introduction. 143 Mic...

SPM Form 4 Physics Chapter 1. 141 Consistency, Accuracy and Sensitivity. 1 Precision is the ability of an instrument in measuring a quantity in a consistent manner with only a small relative deviation between readings. 2 The precision of a reading can be indicated by its relative deviation. 3 The relative deviation is the percentage of mean deviation for a set of measurements and it is defined by the following formula:. 2 The measurement is more accurate if its number of significant figures increases.

SPM Form 4 Physics Chapter 1: 1.2.4 Scientific Notation
http://physics401.one-school.net/2008/06/scientific-notation.html
SPM Form 4 Physics Chapter 1. Scientific Notation (Standard Form). Also known as Standard index notation) is a convenient way. To write very small or large numbers. In this notation, numbers are separated into two parts, a real number. With an absolute value between 1 and 10 and an order of magnitude. Value written as a power of 10. Physical quantities that are very big or very small need to be written in the standard form so that it is neat, simple and easy to read. 1 2,600 = 2.6 x 10. 36 000m per 1440s.
