Physics (a)


·         Mass is measured in kg. This is found using a balance or a scale.

·         Volume is measured in cm3 or m3. A regular objects volume is found using a ruler. An irregular objects volume is found by displacing water.

·         Density= mass/volume (mass divided by volume)

·         Volume= lengthxwidthxheight


How to find Density


1.       Weigh the object on the scales to find the mass.

2.       Times the length, width and height together once you have measured it to get the volume.

3.       Divide the mass by the volume for the density.

Things that are very dense: metal, stone and glass

Things that are not very dense: feathers, polystyrene, paper and plastic.

Temperature & Heat

·         Heat is form of energy which is measured in joules.

·         It tells you how warm or cold something feels.

·         Temperature is the measure of heat.

·         It is measured in degrees Celsius, degrees Fahrenheit and Kelvin

·         It is measured using a thermometer


Mass and temperature affect the amount of heat an object has.




·         Particles that are very close together can transfer heat energy as they vibrate.

·         This type of heat transfer is called Conduction.

·         Conduction is the method of heat transfer in solids but not liquids and gases.

·         When we heat an object the particles vibrate and pass the heat energy along.






HKS25 :)

its helpful :)


Its actually better than the so called revision guides! Good stuff!!
