The Indian Olympiad Qualifier in Mathematics (IOQM) is a national exam for students in grades 8-12. It's used to shortlist students for HBCSE's Mathematical Olympiad program. Students must be under 20 years old by June 30 of the IMO year and cannot have passed Class 12.
The program was renamed to National Talent Search Scheme with the NTSE examination now being conducted for classes X, XI, and XII. Currently, the NTSE exam is conducted only for 10th class students in India in two phases with subjects relating to Mental Ability Test and Scholastic Aptitude Test (SAT) for 100 marks each. [6] [7]
There are two main descriptions of motion: dynamics and kinematics.Dynamics is general, since the momenta, forces and energy of the particles are taken into account. In this instance, sometimes the term dynamics refers to the differential equations that the system satisfies (e.g., Newton's second law or Euler–Lagrange equations), and sometimes to the solutions to those equations.
The expression in brackets is a total or material derivative as mentioned above, [75] in which the first term indicates how the function being differentiated changes over time at a fixed location, and the second term captures how a moving particle will see different values of that function as it travels from place to place: [+ ()] = [+] =.
The two dots on top of the x position vectors denote their second derivative with respect to time, or their acceleration vectors. Adding and subtracting these two equations decouples them into two one-body problems, which can be solved independently. Adding equations (1) and results in an equation describing the center of mass motion.
A tautochrone curve or isochrone curve (from Ancient Greek ταὐτό 'same' ἴσος 'equal' and χρόνος 'time') is the curve for which the time taken by an object sliding without friction in uniform gravity to its lowest point is independent of its starting point on the curve.
Since the velocity of the object is the derivative of the position graph, the area under the line in the velocity vs. time graph is the displacement of the object. (Velocity is on the y-axis and time on the x-axis. Multiplying the velocity by the time, the time cancels out, and only displacement remains.)
A sample path of an Itō process together with its surface of local times. In the mathematical theory of stochastic processes, local time is a stochastic process associated with semimartingale processes such as Brownian motion, that characterizes the amount of time a particle has spent at a given level.
