Key Differences

When you look around, you will find an array of objects with different size, shape and texture. These objects are made up of matter, which is present in three forms i.e. solid, liquid and gas. All three states of matter possess two things in common, which are mass and volume. Mass is the quantity of matter while volume is the measure of space occupied by the object. The ratio of these two aspects of the matter is known as density. The measurement unit of mass is a kilogram, whereas the … [Read more...]

The basic difference between uniform and non-uniform motion is that the former represents the motion in which the moving body covers the same distance in the same time, but in the case of latter, the body travels unequal distances at the same time. There are millions of objects surrounding us, some of them stay at rest while others are in motion. In our day to day life, you have noticed the motion of different living and non-living things that are on the move like birds, fishes, cars, buses, … [Read more...]

Weather plays a significant role in our lives, as most of our day to day activities are planned according to the forecasting made by the meteorological department for a particular day. It is the intricate phenomenon, which demonstrates changes over very short periods of time, in the atmospheric condition at a given region. On the contrary, climate indicates the weather pattern of a particular place, taken over a long time. Often perceived as being the one and the same thing, these two terms … [Read more...]

The process in which heavy nucleus is broken into tiny nuclei, is called as nuclear fission. On the other extreme, nuclear fusion is defined as the reaction wherein lighter atoms come together and form a heavy nucleus. With the rapid industrialisation, our demand for energy is increasing in the same ratio, because of the change in the way we live and do our work, as we are greatly dependent on machines to do our work, which consumes energy. It implies the strength and power that we require to … [Read more...]

Velocity and acceleration are the two key concepts which are always discussed while studying motion. Velocity can be understood as the speed of a moving body in a particular direction whereas acceleration is any change in the velocity of the object, with respect to time. Motion implies movement; it is the act of moving or more specifically, the change in position of the body, concerning time. Whenever you walk, run or drive you are actually in motion and not only this, flying of birds, … [Read more...]

While conduction is the transfer of heat energy by direct contact, convection is the movement of heat by actual motion of matter; radiation is the transfer of energy with the help of electromagnetic waves. The matter is present around us, in three states, solid, liquid and gas. The conversion of matter from one state to another is termed as a change in state, that takes place due to the exchange of heat between the matter and its surroundings. So, heat is the transition of energy from one … [Read more...]

In your surrounding, you might have observed there are millions of objects, which are created out of matter and the matter comprises of molecules, which is a combination of two or more atoms bonded together. So, in short, atoms are grouped together to form a molecule, which embodies the objects around us. The whole universe is made up of the atom, and they are so small particles of an element, that we are not able to see them through bare eyes or even via microscope, but they do exist in each … [Read more...]

The terms science and technology, are often pronounced in the same breath and used as synonyms, because they are closely intertwined, that their difference is many a time ignored. Science is all about acquiring knowledge of the natural phenomenon along with the reasons for such phenomenon, like Why the sky is blue? Why are leaves green? Why rainfall occurs? What are the colours of the rainbow? How do plants make their food? And so forth. When this knowledge is put to practice, to solve human … [Read more...]

Energy is the strength needed to perform work, while the rate at which work is performed is called power. The unit of measurement in energy is termed as joules, whereas, a watt is the measurement unit of power. A fine line of difference exists in the way we use the word 'work', in our routine activities and in science. As in our day to day life, work entails the physical and mental strain, such as dancing, singing, cooking, bathing washing, learning, etc. However, in science work implies the … [Read more...]

Eclipse alludes to the blocking of light from an astronomical object by the passage of another amidst it. It is an event in which three celestial bodies, i.e. the sun, moon and earth are in tandem. When the moon is in the middle of sun and earth, a solar eclipse occurs, and if the earth is in between sun and moon, it is the case of the lunar eclipse. The reason for the occurrence of the eclipse is that there are two points where the orbit of the moon passes through sun's plane called as … [Read more...]
