physics

branch of science that studies matter, energy, and their interactions

james clerk maxwell

developed the fundamentals of electromagnetism

heinrich hertz

experimentally confirmed maxwells theory using a spark-gap transmitter, showing that electromagnetic waves travel at the speed of light

5. electromagnetism

types of classical physics

mechanics

study of causes of motion, forces, and the behavior of object

thermodynamics

study of heat, temperature, and how work is transferred

acoustic

study of mechanical waves, sound, its production, transmission, and effects

optics

study of properties of light, its behaviour, reflection, refraction, and lenses

importance of physics

• understand how the world works

• develop technology and machines

• improve health and safety

• make everyday tasks easier and more efficient

technology

refers to the way scientific concepts and principles are applied for practical purposes

tools

tangible or intangible product that helps in performing a task, such as laboratory apparatus and software programs

processes

specific methods or procedures that are used to transform raw materials into functional products, such as robotics and three-dimensional printing

products

any tangible and intangible outputs that are created from the utilization of both tools and processes, such as a smartphone

physics and health

plays a vital role in health and medicine because it relies on waves, magnetism, and energy

physics and work productivity

helps people work more efficiently and safely by reducing effort and optimizing energy use

physics and leisure

is at play in many leisure activities we enjoy everyday
