Mass measures the amount of matter an object contains and it is a fundamental property of an object. It remains constant irrespective of the object's location, it is a scalar quantity. The SI unit of mass is the kilogram (kg). On the other hand, weight is a vector quantity and refers to the force exerted on an object due to gravity. The SI unit of weight is the Newton (N).Mathematically, the relation between mass and weight is given by W=mg, W=weight, m= mass, and g=acceleration due to gravity. The g's value varies based on the location. Therefore, while the mass of an object remains constant, the weight can change depending on the gra

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.

According to Newton's third law of motion, every action has an equal and opposite reaction. These action-reaction forces act on different objects. The real-world example is a person walking, when the person takes a step forward, their foot pushes backward on the ground, the ground also exerts an equal and opposite force forward on the person's foot and the person is propelled forward due to the reaction force from the ground. Another real-world example is the rocket launch which expels hot gases downward (action), the gases exert an equal and opposite upward force (reaction) on the rocket and cause upward acceleration. It is an importa

Newton's First Law of Motion is also known as the Law of Inertia. It states that unless acted upon by an unbalanced force, the object in motion stays in motion in the same direction and with the same speed and the object at rest stays at rest. The fundamental concept of inertia is introduced by the first law of Newton which refers to the resistance an object shows to changes in its state of motion. It is an inherent tendency of an object. Inertia is directly proportional to an object's mass which implies that a massive object has greater inertia and will require more force for velocity changes.
Newton's First Law of Motion implies that

The Sequences and Series is introduced as Chapter 8 in Class 11 Maths. A sequence is defined as an ordered list of numbers following a specific pattern or rule, while a series is defined as the sum of the terms of a sequence. there are several key topics discussed in this chapter;
Arithmetic Progression (AP): Arithmetic prograssion is a sequence in which a constant term is either added or substracted in consecutive term. Constant term is called common difference.
Geometric Progression (GP): Geometric Progression is a sequence where each term is multiplied by a constant ratio.
