Equations to use:

force = mass x acceleration

acceleration = force / mass

mass = force / acceleration

acceleration = change in velocity / time taken

Grade thresholds

PHYSICS GCE Advanced Level and GCE Advanced Subsidiary Level Grade thresholds taken for Syllabus 9702 (Physics) in the May/June 2011 examination. The thresholds (minimum marks) for Grades C and D are normally set by dividing the mark range between the B and the E thresholds into three. For example, if the difference between the B and the E threshold is 24 marks, the C threshold is set 8 marks below the B threshold and the D threshold is set another 8 marks down. If dividing the interval by three results in a fraction of a mark, then the threshold is normally rounded down. Grade A* does not exist at the level of an individual component. The thresholds for the syllabus are determined first by adding together the thresholds for the components taken by the candidate. A reduction may be made at the higher grades depending on the correlation of the papers. If the maximum raw marks for the components are not in the weighting/relationship specified in the syllabus, a weighting is applied

All Definitions Needed For A Level (Part 1)

Measurement: Random errors are errors of measurements in which the measured quantities differ from the mean value with different magnitudes and directions. Systematic errors are errors of measurements in which the measured quantities are displaced from the true value by fixed magnitude and in the same direction. Accuracy is a measure of how close the results of an experiment agree with the true value. Precision is a measure of how close the results of an experiment agree with each other. Thermal Physics: The internal energy is a function of state and the total microscopic kinetic and potential energies of the particles  composing the system. The specific latent heat of fusion, L f , is defined as the amount of heat required per unit mass to change a substance from the solid phase to the liquid phase without any change in temperature The specific latent heat of vaporization, L v , is defined as the amount of heat required per unit mass to change a substanc
