What is the difference between biology, physics and chemisty?

Laurenn_x: What is the difference between biology, physics and chemisty?
I have to write between 1/2 to a whole A4 sheet on what is the differencce between biology, physics and chemisty for my homework. Please dont just write a few sentances. The more you right the more i will pick you for best asnwer. Also i wont copy and paste your answer, just will use ideas and put in my own words

Thanks x

Biology is about Organism
Physics is about Forces
Chemistry is about Reactions

Answer by Anna
Biology is the science of studying living organisms. Prior to the nineteenth century, biology came under the general study of all natural objects called natural history.

Chemistry (from Egyptian kēme (chem), meaning “earth”[1]) is the science concerned with the composition, behavior, structure, and properties of matter, as well as the changes it undergoes during chemical reactions.[2] It is a physical science for studies of various atoms, molecules, crystals and other aggregates of matter whether in isolation or combination, which incorporates the concepts of energy and entropy in relation to the spontaneity of chemical processes. Modern chemistry evolved out of alchemy following the chemical revolution (1773).

Physics (Greek: physis – φύσις meaning “nature”) is a natural science; it is the study of matter[1] and its motion through spacetime and all that derives from these, such as energy and force.[2] More broadly, it is the general analysis of nature, conducted in order to understand how the world and universe behave.

Hope u’ve got what u needed…

Physicists wanted to be mathematicians, but were too sloppy for math
Chemists wanted to be physicists, but physics was too detailed
Biologists wanted to be chemists, but chemistry was too dry
Mathematicians wanted to be scientists, but could not deal with the real world

These disciplines differ in their levels of approximation.

Chemistry mainly studies thing at a molecular level (atoms,elements, their interactions), gross properties of matter and how it combines; what makes up materials in the world

Physics mainly studies principles and materials that govern the world – from elementary particles and photons to planets and universes.

Biology studies the lives that spawn from materials characterized by chemists and physicists.
