Laws of Motion

Moment of inertia is one of the fundamental concepts of physics. It was discovered by Galilio Galilei, who said that moment of inertia is a property of a body by its virtue that helps the body resist a change in its motion when an external force is applied to it.  The parallel axis theorem is […]

Speed and velocity are two different entities. Average speed is defined as the total path length traversed by a body divided by the total time taken for the motion to take place. Instantaneous speed is the speed recorded at a specific point of time/at a particular instant. On the other hand, Average velocity implies the

Centripetal force may be called the force which is responsible for keeping a body or an object right in a circular path. This force always acts towards the centre of the path in which it is moving. In this type of force, no displacement of the object takes place due to an inward force. For

Einstein once said that the most incomprehensible thing about the universe is that it is comprehensible. This means that the laws of nature not only apply to Earth but to the universe. With time it has been observed that every place, every particle in the universe follows some regulations called the laws of nature. Laws

The rate of change of displacement of an object, or the change in the object’s location according to a specific frame of reference with regard to time, can be described as velocity. An object’s velocity is a vector quantity, which means. Velocity varies from speed because it includes both magnitude and direction. An object’s speed

Displacement Displacement is the difference in the initial and the final position of an object with respect to its origin. It is a vector physical quantity. The net displacement can be zero but distance can never be zero. The S.I. unit is a metre. Distance Distance is the actual path that is covered by the

Introduction Velocity is a vector amount that refers to ” the rate of change of displacement over a particular interval of time Since velocity is outlined as the rate at which the position changes, this motion ends up in zero velocity when displacement is zero. If a person in motion desires to maximise their velocity,

Introduction Vector is defined as a quantity that has both magnitude and direction. Examples for vector quantity are displacement, velocity, acceleration, force, etc. Vector subtraction and addition does not follow the simple arithmetic rules. A special set of rules are used for vector subtraction and addition.  Vector Addition  The process of addition of two or more vectors together is

Introduction When a body moves in a plane or in a straight line, three characteristics – distance, velocity, and acceleration – are employed to characterize its motion. The term “distance” or “displacement” is self-evident. The rate of change of position is represented by velocity, whereas the rate of change of velocity is represented by acceleration. 

Whether we are humans, animals, birds, fish, trains, cars, or anything else, we are surrounded by a variety of living and non-living things. Some of these things move, while others remain stationary. A body is said to be in motion when it constantly changes its position in relation to time and a stationary object used
