Main Points to be studied in this section

Measurements

• Use and describe the use of rules and measuring cylinders to calculate a length or a volume
• Use and describe the use of a mechanical method for the measurement of a small distance (including use of a micrometer screw gauge)
• Use and describe the use of clocks and devices for measuring an interval of time.
• Measure and describe how to measure a short interval of time (including the period of a pendulum)
• Show familiarity with the idea of the mass of a body
• State that weight is a force
• Demonstrate understanding that weights (and hence masses) may be compared using a balance
• Describe an experiment to determine the density of a liquid and of a regularly shaped solid and make the necessary calculation
• Describe the determination of the density of an irregularly shaped solid by the method of displacement, and make the necessary calculation
