Vectors are the physical quantities which have both magnitudes and directions and obey the triangle/parallelogram laws of addition and subtraction. It is specified by giving its magnitude by a number and its direction, e.g. Displacement, acceleration, velocity, momentum, force, etc. A vector is represented by a bold face type and also by an arrow placed over a letter, i.e. `F, a, b` or `vecF,veca,vecb`.The length of the line gives the magnitude and the arrowhead gives the direction.The point P is called head or terminal point and point 0 is called tail or initial point of the vector OP.Amongst the following

Relative Velocity Every motion is relative as it has to be observed with respect to an observer. Relative velocity is a measurement of velocity of an object with respect to other observer. It is defined as the time rate of change of relative position of one object with respect to another.For example, if rain is falling vertically with a velocity `v_r` and a man is moving horizontally with `v_m`, the man can protect himself from the rain if he holds his umbrella in the direction of relative velocity of rain w.r.t. man.Two bodies are held separated by 9.8 m vertically

Projectile motion is a form of motion in which an object or particle is thrown with some initial velocity near the earth’s surface and it moves along a curved path under the action of gravity alone. The path followed by a projectile is called its trajectory, which is shown below. When a projectile is projected obliquely, then its trajectory is as shown in the figure below Here velocity `u` is resolved into two components, we get (a) `u cos theta` along `OX` and (b) `u sin theta` along `OY`.The example of such type of motion

Uniform Circular Motion When an object follows a circular path at a constant speed, the motion of the object is called uniform circular motion. The word uniform refers to the speed which is uniform (constant) throughout the motion. Although the speed does not vary, the particle is accelerating because the velocity changes its direction at every point on the circular track.The figure shows a particle P which moves along a circular track of radius `r` with a uniform speed `u`.A circular
