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 momentu

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 label

Inertia is the body's inherent property to resist any change in its state of rest or motion. Newton's First Law of Motion says that unless an external force is applied to an object, it will not change its state (rest or motion). Hence, the first law of Newton defines inertia. It also says that if th

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 equ

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

When two waves of the same amplitude, frequency and speed travel in opposite directions and collide with each other, then a standing wave is formed. It is usually seen in the bounded medium, like a string fixed at both ends. It is different from the travelling waves and does not appear to move along

According to the principle of superposition, when two or more waves overlap in space, due to each individual wave, at any point the displacement is the vector sum of the displacements. The principle of superposition also explains phenomena like interference where waves combine to amplify or cancel o

Mechanical waves are of two types - transverse waves and longitudinal waves. It requires a medium to travel. The medium particles vibrate perpendicular to the direction of wave propagation in the case of transverse waves.  However, the particles oscillate parallel to the wave direction in the l
