Volume, Density, Area, Speed, Time, Mass Flashcards
What is the method of finding the volume of a regular solid?
Length ✖️ width ✖️ height
What is used to measure the volume of a liquid?
A burette/pipette
How do you find the volume of an irregular solid?
Method of displacement (overflow can)
What is density?
The density of a substance is its mass per unit volume
What is the S.I unit of density?
Kg/m-3
What is the formula to find somethings density?
Mass divided by volume
To find the density of a liquid you must….
1) use a burette/pipette to find its volume
2) weigh a beaker
3) weigh the beaker with the liquid in it
4) take the weight of the beaker from the weight of the beaker with the liquid in it to get the mass of the liquid
5) divide the mass by the volume
How do you find the density of an irregular solid?
1) Weigh the object to get its mass
2) get the volume by using the displacement method
3) divide the mass by the volume
What is the mass of an object?
The mass of an object is the amount of matter or stuff in it
What is area?
The area of a shape is the amount of surface enclosed within its boundary lines
How do you find the area of a square?
Length ✖️ length
How do you find the area of a rectangle?
Length ✖️ width
How do you find the area of a triangle?
Half the base ✖️ the perpendicular height
How do you find the area of a circle?
Pie (3.14?) ✖️ the radius squared
The S.I unit of area is the…?
Square metre (m-2)
What is volume?
The volume of an object is the amount of space it takes up
What is the S.I unit for volume?
The cubic metre (m-3)
Volume = ….
Volume = length ✖️ width ✖️ height
When do substances float in water?
If they are less dense than the water
What is the speed of an object?
The speed of an object is the distance it travels per unit time
What is the unit for speed?
Metres per second (m/s)
How do you calculate speed?
Distance travelled divided by time taken
What is velocity?
The velocity of an object is its speed in a certain direction
What is acceleration?
Acceleration is the rate of change of velocity (or speed)
What is the unit of acceleration?
Metre per second per second (m/s/s)
How do you calculate the acceleration?
Acceleration = change in velocity
divided by
Time
What is deceleration?
When the object is losing velocity
What is the S.I unit of length?
The metre
What can be used to measure lengths?
Metre stick, ruler, measuring tape, callipers, vernier callipers, opisometre, trundle wheel
What is the mass of an object?
The mass of an object is the amount of matter/stuff in it
How do you get an objects mass?
Weigh it
What is the S.I unit of mass?
Kilogram
How many grams is in a kilogram?
1000
What is the S.I unit of time?
The second
What is temperature?
The temperature of an object is the measurement of how hot/cold it is
The unit of temperature is the…. ?
Degrees Celsius
What is used to measure temperature?
Thermometer
What is pie?
3.14
