Q1. What is Science?
Ans: Science; The Knowledge gained through observations and experiments is called science”
Science is derived from the Latin word “Scientia” meaning “knowledge” Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Physical Sciences:
Physical sciences deal with the study of non-living things
Biological Sciences:
Biological sciences deal with the study of living things.
Q 2. Define physics. Describe some branches of physics.
Ans: Physics:
The branch of science that deals with the properties of matter, energy, and their mutual relationship is called physics. Main Branches of Physics:
The main branches of physics are as follows.
- Mechanics:
The branch of physics which deals with the study of the motion of objects, their causes, and their effects is called mechanics. 2. Heat and Thermodynamics:
The branch of physics that deals with nature, properties, uses, effects, and modes of transfer of heat are called heat and thermodynamics 3.
Oscillations and Waves:
The branch of physics that deals with the study of oscillations (to and fro motion) and waves is called oscillations and waves
- Optics:
The branch of physics that deals with the nature and properties of light like reflection, refraction, diffraction, interference, propagation, and dispersion is called Optics
- Electricity and Magnetism:
The branch of physics which deals with the study of charges at rest and in motion, their effect and their relationship is called electricity and magnetism.
