Physics influence our lives as follows aspects
At home
They include
i) All tools and
machinery: such as Crowbars, Hammers, door
handles, cutlery, hinges, car jack, pulleys, tillage implements etc, made by
knowledge of physics
ii) Electrical appliances: such as cooker, iron, heater, electric lamps,
washing machine etc, made by knowledge of physics
Medical field
They include;
i) Machines such laser, x-ray,
incubators, ultrasound and infrared machines
ii) The knowledge used in
handling and even actual use of these machines are based on the knowledge and
skills acquired in Physics.
Source of energy
They include;
i) Batteries and generators
provide electrical energy
ii) Bulbs they provide light
energy
iii) Speaker gives us sound
energy
Transport
All Vessels used in transportation is results of concept
of physics. For Example, cars, ships, aero plane, trains etc
Communication
All Devices used in communication systems is results of
concept of physics. For Example, telephones, modems, television, cables etc
Entertainment
Physics enable people to enjoy a variety of leisure
activities as is evident in photography, digital appliances, exercise machines
and other sport equipment.
Industry
Physicists have been able to come up with tools and
process that have resulted in advanced technological equipment and new
discoveries.
In schools
The instruments and apparatus used in school laboratories
are made through the application of the knowledge and skill acquired in a
Physics class.
Importance of Learning Physics
i) The study of physics
enables us to answer many question concerning physical properties of matter. For
example, “why sky is blue?”
ii) Enable different people to
acquire skills that required in different profession. For Example, engineering,
teaching and architecture
iii) Enable us to designing and manufacture
different items. For Example, dry cell, simple machines, mobile phones etc.
iv) Enable us to enjoy since we
study practically
