Measurement In Physics Flashcards
Sl units
To make sure everyone in the world can understand each other we all use the same units called Sl units.
Metre stick
Is used to measure length
Stopwatch
Is used to measure time
Graduated cylinder
Used to measure the volume of a liquid
Thermometer
Used to measure temperature
Newton meter
Used to measure Force
Ohmmeter
Used to measure Resistance
Measuring Length
A metre stick or ruler measures straight lines
Opisometer
An opisometer can be used to measure short curved lines for example a road or river on a map
Trundle Wheel
Used to measure long curved lengths for example around a flower bed
Vernier Callipers
To find the diameter or width of a solid object for example marble or a or a piece of piping
Measuring Area
Area is how much space something covers
Mass
Mass is the amount of matter in an object
It is measured in labs using an Electronic balance
Measuring volume
Volume tells you how much space something takes up.
It measures in m3(or cm3,ml or liters).
Measuring irregular volume
The volume is measured by a graduated cylinder and a over flow can.
A stone or potato is dropped into an overflow can and the water then spills out into the graduated cylinder which can then give you the volume
