Lesson 03
Last time we were talking about what is physics and what do we study in physics.
Physics is a natural science that studies different phenomena in nature.
We can divide it in two groups: theoretical physics and applied physics.
Do you know the difference between these two?
We can also divide it in two groups:
classical physics from 1600 until 1900 and modern from 1900.
In physics we study what happens between objects in nature:
we can study different objects (humans, cars, balls, buildings, atoms) and
forces (gravity, electromagnetic force, strong and weak nuclear force)
Todays subject "Four fundamental forces"
Gravitation
Electromagnetism
Strong force
Weak force
Work in the same groups again and find out
1) Where can we find this force acting
2) Is it attractive or repulsive
3) What is the mediator
4) Is the force strong or weak
Then go back to your place and tell the others what you have learned
