Law of Motion (NCERT Notes)
Newton's Three Laws of Motion. Newton's three laws of motion may be stated as follows: Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it. Force equals mass times acceleration [ ]. For every action there is an equal and opposite reaction.

Statistics in 10th Class Mathematics
Statistics is a mathematical body of science that pertains to the collection, analysis, interpretation or explanation, and presentation of data, or as a branch of mathematics. ... Descriptive statistics can be used to summarize the population data.
Motion in Plane (Physics)
Motion in a Plane. Motion in a plane is also referred to as a motion in two dimensions. For example, circular motion, projectile motion, etc. For the analysis of such type of motion, the reference point will be made of an origin and the two coordinate axes X and Y.
Motion in Striaght Line (Physics)
Motion in a Straight Line. If an object changes its position with respect to its surroundings with time, then it is called in motion. If an object does not change its position with respect to its surroundings with time, then it is called at rest.
Mathematical Reasoning
Foundations for Mathematical Reasoning is the common starting point for all three mathematics pathways and is designed to build the mathematical skills and understanding necessary for success in a quantitative literacy, statistics, or algebra course.
Conic Sections (NCERT NOTES)
They are called conic sections, or conics, because they result from intersecting a cone with a plane as shown in Figure 1. PARABOLAS. A parabola is the set of points in a plane that are equidistant from a fixed point (called the focus) and a fixed line (called the directrix).
Straight Lines in 12th Mathematics
A line traced by a point traveling in a constant direction; a line of zero curvature; "the shortest distance between two points is a straight line" line - a length (straight or curved) without breadth or thickness; the trace of a moving point.
Relations and Functions in 12th Class Mathematics
A "relation" is just a relationship between sets of information. Think of all the people in one of your classes, and think of their heights. The pairing of names and heights is a relation. In relations and functions, the pairs of names and heights are "ordered", which means one comes first and the other comes second.
Amines NCERT Notes
Amine Structure Amines that have one of their three hydrogen atoms replaced by an alkyl or aromatic substituent are referred to as primary amines. Secondary amines are those that have two substituents and one hydrogen bonded to a nitrogen.
Solid States (NCERT Notes)
Solid. Solid, one of the three basic states of matter, the others being liquid and gas. (Sometimes plasmas, or ionized gases, are considered a fourth state of matter.) A solid forms from liquid or gas because the energy of atoms decreases when the atoms take up a relatively ordered, three-dimensional structure.
Chemistry in Everyday Life
Chemistry is a big part of your everyday life. You find chemistry in daily life in the foods you eat, the air you breathe, cleaning chemicals, your emotions and literally every object you can see or touch.
Solutions NCERT Notes
A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase. A solution consists of a solute and a solvent. ... For example, in a saline solution, salt is the solute dissolved in water as the solvent.
