The strain of an elastic object or material is proportional to the stress applied to it. Stress ∞ Strain
The periodic movement transmits energy from one place of a medium to another but the particles of the medium are not displaced permanently, which is called a wave.
A sound or sounds caused by the reflection of sound waves from a distant surface back to the listener is called an echo.
Sound pollution refers to an audibility limit exceeding 20,000 Hz that causes different health-hazards to the listeners.
In science, particularly in physics, the concept of space and time is very important. We need the concept of space and time to describe any event because without it we cannot get a clear idea about space and time of the event. The concept of space is in vogue from ancient times to locate the … Read more
The branch of science which deals with matter and energy is called physics. The main objectives of physics are to establish the relation between matter and energy and to express it quantitatively on the basis of observation, experimentation, and analysis. Physics, science that deals with the structure of matter and the interactions between the fundamental constituents of … Read more
The process where liquid substances turn into vapor is called evaporation.
