During bomb blast the particles are scattered in various dir ection explain why?
This is because of conservation of momentum of the whole system. Since external force is not acting. So each particle goes in the direction opposite to the direction of some other particles, or opposite to the net velocity of a bunch of particles depending on its mass. So the Centre of mass is at rest.
due to conservation of momentum
Since no external forces are acting..(only internal forces are there)..therefore momentum is conserved!
Conservation of momentum, nothing else conceptually
Conservation of momentum M changes to m1,m2,..........mases with different velocity but momentum before and after explosion is conserved
Bcoz of law of cnsrvtn of momentum.
It is because momentum before and after blast is same....so after blast the velocity vector nullifies each other to make zero resultant velocity...and multiplied by scalar quantity mass..the final momentum remains zero.....law of conservation of momentum colud be the reason behind this...
On blast the particles get k.e. and p.e. in diff. Direct ions
This is because the explosive is in middle and is surrounded also the explosion generally starts from core but this does not matter much as the reaction time is very less thus when it explodes it exerts force in all directions and hence particles are scattered in all directions
