Properties of Matter
            Introduction :-
 
In the previous chapters, we have been discussing the motion of bodies either in horizontal or vertical direction. But we see that whenever a particle in projected upwards at a certain angle ( but not vertical) we find that the particle trances some in the air and falls in the air and falls on the gourd at a point, other than the point of projection. If we study the motion of the practical, we find that the velocity, with which the particle was project, has two components.
A particle, moving under the combined effect of vertical and horizontal forces, is called a project.
