Learning Made Easy
In physics, a physical quantity is anything that can be measured, and it falls into one of two categories: scalar and vector quantities. Scalars are defined solely by their magnitude, while vectors require both...
echanical energy is of two types – potential and kinetic energy. The kinetic energy of the body is due to the virtue of its state in motion, whereas potential energy is the stored-up energy...
In chemistry, all types of changes can broadly be classified into physical and chemical changes. In this post, we will learn about the difference in physical and chemical change with examples- The characteristics of...
In Physics, we define . As per the law of conservation of energy, – however, it can be changed from one form to another. In this post, we will learn about the different forms...
Ernest Rutherford conducted the gold foil experiment or the alpha particles scattering experiment in the year 1911. Based on the results, Rutherford presented his atomic model, which laid the foundation of modern-day’s atomic theory....
Some basic physical and chemical properties of metals that differentiate them from non-metals and metalloids are as follows: Physical Properties of Metals: Usually, metals are hard, opaque, possess luster, and conduct heat and electricity....
We can call only those things dead, which once lived and followed the life cycle. For example, we can call a block of wood and leather dead because they come from organisms that once...
When an object’s position changes with time, we say it is in motion. Different objects have different types of motion. For example, a train moves straight along its track, a fan rotates around its axis, and...
In my earlier post Elements and Compounds, we learned, that so far we have discovered total of 118 types of elements. Out of the 118 elements – 94 are metals, 17 are nonmetals and...
Mass and weight are two common science terms that people often mix up. Kids especially use them interchangeably without understanding that there is a difference between mass and weight. Yes, It’s true—mass and weight...
