Physics extends to your daily life to describe the motion, forces, and energy of the ordinary experience. Physics is at work in tasks such as walking, driving a car or using a phone. Knowledge of physics is helpful in everyday situations as well as in non-scientific tasks.
For example, physics helps you understand:
How food is cooked in a microwave oven,
Why a radiator helps to dissipate the heat of a car engine, and
Why a white ceiling helps to keep the inside of a house cool.
Thousands of such questions can be answered and explained via physics.
Physics is the foundation of many critical scientific disciplines, such as chemistry is rooted in quantum physics which describes the in-depth study of atoms and molecules. Physics is also applicable in most branches of engineering. In architecture, physics is pivotal to determining structural stability, acoustics, heating, lighting and cooling systems for buildings. In Geology, the study of non-living parts of the Earth, such as the study of atmosphere, lithosphere, hydrosphere, earthquakes, storms, volcanoes, and other natural disasters, such as floods, droughts, and extreme heat on the Earth’s surface. Some disciplines, such as chemical electrodynamics, optics, thermodynamics and modern physics, are important branches of physics for studying natural phenomena. Physical science also describes the chemical processes in the human body through biophysics. Physics is implicated in medical diagnoses, such as X-rays, magnetic resonance imaging (MRI), and ultrasonic blood flow measurements. Physics can also explain what we perceive with our senses, such as how the ear detects sound or how the eye detects colour.
