Key Differences

In our daily life, we encounter many changes in our surroundings, though we do not notice them, such as souring of milk, rusting of iron, stretching of a rubber band, bread becoming toast, melting of wax, liting of a match, etc. All these changes that take place around us are physical change or chemical change. Physical changes are the changes that change the physical traits of the substance, without making any change in their internal structure. On the other hand, a chemical change is one … [Read more...]

Everything that surrounds us is either living or non-living and the only characteristic that bifurcates the two is life. All living things like plants, animals, insects, birds, microorganisms, etc. have one feature in common and that's life. So, living things implies all those creatures of nature, that has life. On the other hand, non-living things such as bottle, pen, chair, door, computer, mobiles, etc. are the one's who are not alive. Living things are composed of units called cells, which … [Read more...]

Everything that surrounds us, such as air, food, water, plants, animals, vehicles, clothes and so forth is made up of matter. The matter is a collection of particles and is anything that has mass and occupies space. There are three fundamental states of matter, i.e. solid, liquid and gas. The states of matter take place due to the variations in the molecules of matter. The size and shape of a solid object is definite. Nevertheless, if we talk about the other two states of matter, that is … [Read more...]

Energy implies as the object's capability to perform work. It is something that cannot be created or destroyed but can only be transformed. An object loses its energy, when it performs work, whereas it gains energy when the work is performed on it. Energy is broadly classified as kinetic energy and potential energy. While kinetic energy is the energy which an object contains because of a particular motion. On the other hand, potential energy is the stored energy, because of its state of rest. … [Read more...]

While mass measures, how much matter is present in an object. Weight measures how strongly an object is pulled due to gravity. These two terms are often encountered by us in our day to day life. Whenever we discuss the weight of the body, we actually talk about its mass, but these two are not synonyms, in fact, these two are different notions. Due to the lack of knowledge people use the two interchangeably, which is incorrect, as mass is the fundamental property of matter whereas weight is … [Read more...]

Scalar quantity refers to the quantity, which has only magnitude and no direction. On the other hand, vector quantity implies the physical quantity which comprises of both magnitude and direction. Physics is a science based on mathematics. While studying physics, we go through a number of concepts and notions, which rely on mathematics. The mathematical quantities explaining the motion of a body are bifurcated into two groups, i.e. scalar quantity and vector quantity. For a layperson, the … [Read more...]

In physics, distance and displacement are used to indicate the length between two points. However, these two are not one and the same thing. While distance is the length of the actual path between two locations, displacement, on the other hand, is the length of the shortest path between two locations. So, the distance tells us, how much path is traveled by the body, during motion and the displacement gives us an idea of how far the body is from its starting point, and that too in which … [Read more...]
