Class 11

An example of the periodic motion is Earth's revolution. In this, the motion repeats itself after regular intervals of time. In oscillatory motion, the object moves back and forth about a mean position like a vibrating spring or pendulum. It is a type of periodic motion. Although, oscillatory motions are periodic, however, not vice versa. Oscillatory motion typically follows sinusoidal patterns and involves a restoring force.

In Simple Harmonic Motion (SHM), the restoring force is directly proportional to the displacement from the mean position. It is a periodic motion and acts in the opposite direction. SHM follows the equation, F=? kx, where k is the force constant and x is the displacement. Simple Harmonic Motion is characterized by constant frequency, sinusoidal oscillations, and energy interchange between potential and kinetic forms. Examples are the vibrating springs,  the motion of a pendulum (for small angles), and molecules in a lattice.

Statistics carries a weightage of 8-10 marks in the class 11 annual exams. For sure it proves that this chapter is a high scoring chapter, questions aremostly based on data and straight forword formulas. We have provided NCERT Solutions for Statistics, which can be really helpful in coving all the topics of the chapter and equip you with enough tools to get good marks in class 11 annaul exams.

All competitve exams mostly ask question which are complex in nature and include advance level problems. Students can only solve these problems through strong fundamentals. Students can use Class 11 Math NCERT Solutions of Statistics to build strong conceptual clarity with step-by-step problem-solving, which can later lead to advance level problem solving.

As per the NCERT definition, Statistics is the study of how to collect, organize, analyze, and interpret numerical data. Class 11 Stastics  covers topics like measures of dispersion such as range, mean deviation, variance, and standard deviation. Students can access and download Stastics NCERT Solution PDF for understanding the chapter well. We have provided the link below;

Energy is measured in joules (J). It is the capacity to do work while power is the rate of using energy or doing work. Power is measured in watts (W). One watt equals one joule per second. Power talks about how fast the work is done, and energy is about how much work is possible.
