Error Systematic or Random error
Scale error Systematic error
Zero error Systematic error
Parallax error Systematic error if you always view the dial from the same angle. Random error if you view the dial from a random angle each time.

## How do you record a measurement?

1. Immediately record the measurement after it is read. Call out the measurement continuously until you have recorded the measurement. …
2. Record the measurement directly onto the sheet. …
3. Record measurements clearly and neatly, the same way every time.

## How closely a measurement matches the same measurement when repeated?

Accuracy is how close a measurement is to the correct value for that measurement. The precision of a measurement system is refers to how close the agreement is between repeated measurements (which are repeated under the same conditions).

## What is the relationship between the precision and the uncertainty of measurement What is the relationship between the accuracy and the discrepancy of a measurement?

The precision of a measuring system is related to the uncertainty in the measurements whereas the accuracy is related to the discrepancy from the accepted reference value. Uncertainty is a quantitative measure of how much your measured values deviate from one another.

## What is the precision of a measuring instrument?

The closeness of two or more measurements to each other is known as the precision of a substance. If you weigh a given substance five times and get 3.2 kg each time, then your measurement is very precise but not necessarily accurate. Precision is independent of accuracy.

## What is error physics?

In Physics, an error is defined as the difference between the actual value and the calculated value of any physical quantity. There are two types of errors in physics: Random Errors. Random error occurs when repeated measurements of the quantity give different values under the same conditions.

## How do you measure a distance?

Straight lines

A quick way to measure distance is to count each square you cross on the map. On your Ordnance survey map each grid square measures one kilometre from side to side and from top to bottom. If you go diagonally across a square, the distance will be a bit longer – about 1.5 km.

## What is a zero error?

zero error

Any indication that a measuring system gives a false reading when the true value of a measured quantity is zero, eg the needle on an ammeter failing to return to zero when no current flows. A zero error may result in a systematic uncertainty.

## How is the precision of a measurement related to the least count?

Any measurement made by the instrument can be considered repeatable to no less than the resolution of the least count. The least count of an instrument is inversely proportional to the precision of the instrument.

## What is a measure of the duration of an event taking place?

The duration of an event or state is the time that it lasts. Courses are of two years’ duration.

## Is the measure of duration between successive event?

The interval between two events is called Time.

## Can time be defined?

Physicists define time as the progression of events from the past to the present into the future. Basically, if a system is unchanging, it is timeless. Time can be considered to be the fourth dimension of reality, used to describe events in three-dimensional space.

## What is the duration elapsed between one event and the next?

Answer: Interval between two events is known as Duration.

## Which corresponds to the interval between two events received by an object?

A state corresponds to the interval between two events received by an object. The state of the event depends on the past event.
