- 1What are SI units?SI units are the international base units for measurement.
- 2What are the SI units for: Time Length Mass TemperatureTime- seconds
Length- meter
Mass- Kilogram
Temperature- Kelvin - 3What are the SI units for: Amounts of something Electric current Luminous substanceAmounts of something- mole
Electric current- ampere
Luminous substance- candela - 4What pieces of equipment could be used to measure length?-Rule
-micrometer
-vernier calipers - 5How do you read a vernier caliper?
- 6How do you read a micrometer?
- 7What is volume?Volume is the quantity of space an object takes up.
- 8How can volume be measured>Volume can be measured using
-a measuring cylinder
-using formulas
-using a displacement can - 9Formula for volume?volume of block=length x width x height
volume of cylinder= π x radius2 x height - 10How can time be measured?Time can be measured on and analogue or digital stopwatch
- 11When is finding the period useful?Finding the period is often easier to measure than short time intervals
- 12How do you find the time for one swing?To find the time for one swing you can set up a pendulum.
you measure the time it takes for 10 swings to occur
then divide the time by the amount of swings - 13How can the mass of objects be measured?The mass of objects can be measured using a balance
- 14How can you measure the volume of a small solid?The volume of a small solid can be done in a measuring cylinder.
-Partially fill the cylinder and record the volume
-Then place the object in and record the volume
-The increase in level is volume of the solid - 15How is a displacement can used?-Fill can (water reached spout)
-slowly submerge object
-record volume in beaker.
- 16How is density calculated?density = mass
------------
