Speed and velocity are two different entities. Average speed is the total path length traversed by an object divided by the time taken for the motion. Instantaneous speed is the speed recorded at a specific point in time. On the other hand, average velocity implies the change in position of an object (displacement) divided by […]

Class 11, IIT JEE, Kinematics, Physics, Relative velocityFinding the integral involves the sum of the areas. Similarly, definite integrals are helpful to calculate the area within the start and endpoints between which the area is occupied; this can be said to be the limits. If we take [a, b], as the limit points to find the area of the curve f(x), concerning

Class 11, IIT JEE, Kinematics, Motion in a straight line, PhysicsAntiderivative or integration is the addition of seemingly infinitely small data put together by the process of integration. Tracing all the way back to Greek integration has been a part of the maths curriculum long back; however, it was during Newton’s time that it was realised that both integration and differentiation are inverse operations. So

Class 11, IIT JEE, Kinematics, Motion in a straight line, PhysicsHooke’s Law is a law of physics used to solve problems in the field of elasticity. Hooke’s Law equations prove that the force (F) required to expand or contract a spring by some distance has a linear measure to the distance. The basic Hooke’s Law equation is Fs = kx, where k is a constant

Class 11, IIT JEE, Kinematics, Motion in a straight line, PhysicsDistance can be termed as the overall movement of any mass, regardless of direction. It can be defined as the amount of ground covered by an item, regardless of its starting or ending position or the addition of all the distances covered between n numbers of specific points. Displacement can be termed as the shift

Class 11, IIT JEE, Kinematics, Motion in a straight line, PhysicsIntroduction: One of the essential engineering tests is the bending or fracture of an object or material, and a characteristic showing that it is young’s modulus of elasticity. It is the unchanged-able fundamental property of a material. This measures how easy the material is to stretch or deform. In this article, we will get into

Class 11, IIT JEE, Physical World and Measurement, Physics, SI units and fundamental quantitiesThe resistance of a fluid (liquid or gas) to a change in shape or movement of adjacent sections relative to one another is called viscosity. The term “viscosity” refers to the resistance to flow. The mass of a material substance per unit volume is called Density. Density is calculated using the formula d=M/V, where d

Class 11, IIT JEE, Physical World and Measurement, Physics, SI units and fundamental quantitiesA physical constant, also known as a basic physical constant or a universal constant, is a physical quantity that is universal in nature and has a constant value across time. A mathematical constant, on the other hand, has a fixed numerical value but does not entail any physical measurement. The speed of light in vacuum
Introduction A number is always the measured value when measuring a physical quantity. Using this number only makes sense if the corresponding unit has been given. A measurement’s outcome has a numerical value and an associated unit of measure. Consider the weight of a human body, which weighs three kilograms. In this situation, employing a
