Physics 1 - Length and time

In this video I show how to:
- Use and describe the use of rules and measuring cylinders to find a length or a volume
- Use and describe the use of clocks and devices, both analogue and digital, for measuring an interval of time
- Obtain an average value for a small distance and for a short interval of time by measuring multiples (including the period of a pendulum).
- Understand that a micrometer screw gauge is used to measure very small distances
