Introduction to Physics
Physics and meteorology
Meteorology deals with the study of weather and climate. Meteorologists use an instrument
like rain gauge in Figure 1.5 (a) which is designed and constructed using the principles
of physics to measure rainfall. A wind vane in Figure 1.5 (b) uses physics principles to
measure direction of the wind.

Physics and astronomy
Astronomy deals with the study of objects that compose the physical universe. It involves
the study of stars, planets, satellites, nebulae, galaxies as well as the distribution of
matter and energy in space and time. Due to its complexity, astronomy uses principles,
theories and laws of natural science, engineering, technology and mathematics (STEM).
Therefore, physics plays a crucial role in astronomy. For example, the laws of planets
and other objects present in the solar system are shown in Figure 1.6.

Task 1.2
Search from different resources such as online sources then write short notes on how
physics is related with other subjects apart from natural science.
