Some important points in "Collisions" that we generally
ignore and make mistakes without knowing the meaning
of them:

1)Line of Impact:

When two bodies collide, their surfaces are in contact while
collision.If a line is drawn perpendicular to the common Tang
ent to the surface at the point of contact,the line is called
as "Line Of Impact".

2)Direct Impact:

When the centres of mass of the colliding bodies r initially
moving along the line of impact,impact is called as "Direct
Impact" or we say it "Head on Collision".It should be known
that after " Direct Impact " bodies continue to move along
the "Line of Impact".

3)Oblique Impact:

When centres of mass of the colliding bodies are not moving
initially along the line of Impact, then the impact is called
as "Oblique Impact".

Hope it is useful.
Cheers!!!!!!!!!!!!!
