Momentum has both magnitude and direction and it is a vector quantity. The direction of the momentum is the same as the direction of the velocity. It quantifies the "quantity of motion" of an object and reflects how fast it is moving and how much mass the object has, the standard SI unit for momentum is kilogram-meters per second (kg m/s). A heavier object moving a the same velocity as the lighter object will have greater momentum. Also, an object moving at a higher velocity will have higher momentum than the same object moving at a lower velocity.

When all the forces act on a single object, a free body diagram (FBD) graphically represents these forces. It helps in analyzing the net effect of the forces by isolating the object from its environment. An arrow pointing in the direction of a force represents a force and its magnitude is also labeled. FBDs allow systematic application of Newton's laws and hence are crucial in solving mechanics problems. For example on an inclined plane, in a block, the FBD helps identify normal, gravitational, and frictional forces acting on the block.

NCERT Class 12 Chemistry Amines intext solutions are mentioned in the class textbook. 

The Geometric Mean is the mid term between two numbers in a Geometric Progression (GP), Students can check the important formula for the geometric mean;

The Geometric Mean (G) between them is:

• $G = \sqrt {a \cdot b}$
• Students can use this formula to solve problems in their NCERT textbooks.

An Arithmetic Progression is a sequence of numbers in which the difference between consecutive terms is constant. This constant is called the common difference (d). The Arithmetic Mean between two numbersof an Andhra Pradesh is the number that lies exactly in the middle of them in an AP.

• Arithmetic Mean (A.M.) is given by:

$A.M. = \frac {a + b} {2}$

• If first term (a) and common difference (d) are known:

$S_n = \frac {n} {2} [2a + (n - 1)d]$
