    There are always some questions asking to describe an experiment that shows certain laws or rules. Can anyone suggest some experiments that we should know how to setup or some web links that tell something about this?

    I can think of some examples:
    AS
    Conservation of linear momentum
    Measuring weight of an object making use of the principle of moment
    Newton's first, second and third laws
    Measuring density of solid, liquid and gas
    Radioactive decay with time
    Internal resistance of a cell
    Specific heat capacity of solid and liquid
    specific latent heat of solidfication and of vapourisation of liquid
    Ideal gas equation (P/T=C, V/T=C, PV=C)

    A2
    Frequency and period of an SHM
    Plane polarisation of microwave
    Ripple tank
    Measuring wavelength of light using double-slit and diffraction grating

    btw, can anyone tell me how to measure the density of gas, verify the Ideal gas equation and some experiments about Brownian motion?

    Hi,
    I think we only have to describe the brownian motion experimental set up
    (microscope, smoke cell, light from the side) and what was inferred (smoke particles unevenly bombarded by air molecules).

    As for the experiments I've also seen a question asking how to measure volume changes of a liquid with temperature.
    In the specification, available for download at edexcel, a number of suggested activities are listed with each topic. I guess it's from that list that they set the questions.

    Good luck!

    Using a dilatometer?

    Does it accept datalogging in the experiments on mechanics?
