A position-time graph is a plot of position versus time, showing the relation of the positions of an object with the passage of time. However, it may not show the trajectory of movement to those positions. In physics, position-time graphs describe the velocity of a particle in time and space. They are used to describe […]

Class 11, Kinematics, Motion in a straight line: Distance, displacement, velocity, NEET, PhysicsKinematics is a field of mechanics concerned with the study of motion. Any kinematics study aims to create complex mental models that may be used to describe (and eventually explain) the motion of real-world objects. Position time relation A moving object’s displacement is proportional to its velocity and time. Quicken your pace. Go a step

Class 11, Kinematics, Motion in a straight line: Distance, displacement, velocity, NEET, PhysicsA position-time graph is a plot of positions versus time, showing the relation of positions to time in space or time, but may not show the trajectory of those positions as they move. In physics, position-time graphs describe the velocity of a particle in time and space. The graph depicted shows the velocity of a

Class 11, Kinematics, Motion in a straight line: Distance, displacement, velocity, NEET, PhysicsDifferentiation is a technique for analysing small changes in one quantity in relation to a unit change in another quantity. The algebraic process of calculating derivatives is known as differentiation. With the help of this technique, small changes can be analysed at a micro-level. Using differentiation, the velocity of a body at a certain instant

Class 11, Kinematics, Motion in a straight line: Distance, displacement, velocity, NEET, PhysicsTo describe the motion of a body, certain physical quantities such as velocity and acceleration are required. The basic motion type is a single particle moving in a straight line. Differentiation of a quantity gives the change in that quantity with respect to the other. It is denoted by the change in Y with respect

Class 11, Kinematics, Motion in a straight line: Distance, displacement, velocity, NEET, PhysicsCalculus is divided into two major concepts: differentiation and integration. Differentiation is a technique for analyzing tiny changes in one quantity in relation to a unit change in another. It’s also used to determine whether a function is growing or shrinking. The area of curved surfaces is calculated using integration. It’s also used to figure

Class 11, Kinematics, Motion in a straight line: Distance, displacement, velocity, NEET, PhysicsIntroduction We all have used the word “temperature” in our daily lives and have developed a common notion for the same, i.e., to refer to hotness or coldness. Hence, when we say that something is hot or cold, we generally use a reference point to express the relative degree of hotness or coldness of a

Class 11, Dimensions of physical quantities, dimensional analysis, NEET, Physical World and Measurement, PhysicsIntroduction: Dimensional analysis and its applications is the study of connections between physical variables using their units and dimensions of measurement. We utilise dimensional analysis to translate a unit between several forms. We must maintain the same unit to facilitate mathematical operations in science and mathematics. Dimensional Analysis is often referred to as the factor

Class 11, Dimensions of physical quantities, dimensional analysis, NEET, Physical World and Measurement, PhysicsThe Dimensions of physical quantities define its nature. When we see an item, the dimensions are the first thing we notice. Indeed, we are characterised or observed in our dimensions, i.e., our height, weight and amount of flesh. The dimension of a body refers to its relation to fundamental quantities. When we define a quantity’s

Class 11, Dimensions of physical quantities, dimensional analysis, NEET, Physical World and Measurement, PhysicsThe number of substances is measured with the help of physical quantities. For example, speed is measured in metres per second, that is, m/s, which is the S.I. unit. It helps us convey the amount of distance travelled in a single second. The unit of luminous intensity is candela. Other physical quantities derived from physical
