This is my first time when my lecturer come to my class. He teach basic physics. before we start study, he give social contract about how to learn in his class. let's jump.
Physics is a study about natural phenomena and energy one thing to other thing. Example of physics in daily activities :

Basic concept of machine by James Watt revolution to be a car. James Watt saw a women boiled water. He asked to him self, why lid pan raise after boiled water. It's happen because there're pressure from boiled water. Energi changing from liquid to vapor. Then he apply to wheel of train, until now evolution to high tech.
Other example like a Ohm law, Kirchoff law, Paraday law, and many other, that simple law often used in daily activity.
