Gravitation

Buoyancy Force Buoyancy, or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. We have come across many daily life observations of sinking objects in water and floating on it. As boats, ships, plastic bottles and straws float on the surface of water, some […]

Thrust In our fifth blog of the series, we discussed forces. As a force is any interaction when unopposed, will change the state of the object. From the same blog we are also familiar with the concept of net force. When a net force is applied in a particular direction in a small fraction of time

From the beginning of the series, we used the term ‘mass’ several times. As a beginner, one always confuses mass with weight. Well, there are very distinct differences in between them. Mass and weight have entirely different definition and characteristics. Mass Mass is more like amount of matter, the things it is made of, or

From our previous blog, we know that earth attract objects with a constant force. Whenever a constant force is applied, velocity starts changing. In our third blog of this series, we already have discussed that change in velocity per unit time is known as acceleration. In this case the acceleration is called acceleration due to

From our previous blog, we know that everybody, possessing some mass, attracts each other. Newton derived a formula that can measure the strength of this attraction. He stated that every object in the universe attracts every other object with a force which is proportional to the product of their masses and inversely proportional to the

In part 5 of this series, we mentioned gravitational force under the types of fundamental forces. Today we are going to discuss the basic introduction of gravitation. In our everyday life we experience a number of activities, phenomena and incidents that happen under the influence of gravitation. We have observed that whenever a ball is thrown upward,
