• close observatory

• detailed listing

• scientific methods

• physio-marking

Describes ‘how-well’ the results of a measurement agree with the accepted value.

• exactness

• precision

• critical point

• accuracy

The total displacement of an object can be stated as:

• difference between final and initial position

• sum of final and initial position

• position of an object after a period of time

• none of the above

This is a series of images showing the position of moving object at equal time intervals:

• motion diagram

• trajectory

• distance graph

• location tracking

It is defined as the ‘valid digits’ in a measurement.

• correctional digits

• rounding numbers

• significant digits

• average digits

Time interval (Δt) states the following:

• difference between distance over time

• relation between distance and displacement

• gap of object every 5s

• difference between two times

What is defined as the change in position divided by time interval:

• average displacement

• average velocity

• constant speed

• average time

The best statement about particle model for an airplane landing-on would be:

• the dots would form an evenly spaced pattern

• the dots are closed together at start, then get farther apart gradually

• the dots are far apart at start, then get closer together gradually

• the dots created slanted line towards up

When an illustration of a moving object is changed to series of ‘single point’ or dots, then it will be called:

• data graphing

• particle model

• point locator

• dotting motion

Which among the following is a magnitude quantity?

• velocity

• force

• mass

• weight
