Homework Statement
While solving problems ,during collision ,we neglect impulse of external forces like gravitational force , spring force , acting on the system .
The cases are
1) An object falling from a height on a pan attached to a vertically hanging massless spring and colliding inelastically to it.
2)Two balls,one thrown vertically upwards ,other moving vertically downwards colliding mid way in air .
Does that mean we can always neglect impulse of all the conservative forces namely spring force,gravitational force,electrostatic force during collision?
Kindly clear my conceptual doubt .
