What force is applied to the impact object?
What force is applied to the falling object? (assuming no deformation)
All assuming no air resistance and no bouncing

The force is
and weight is also a force

I drop a 1kg weight from a meter in height and it decelerates to a stop in 0.1 of a meter (total distance travelled 1.1 meters)

Why is your question expressing weight in kilograms, that is the unit for mass. Weight is expressed traditionally in Newtons?

You should check out def no.s 2,3 &5. Weight in the OP is being used as a concrete noun - ie a lump of metal of known mass.

Oh right. Ok.

So really
1kilogram of mass as we know is 9.81 newtons thus I suppose, 1kg = 9.81 newtons and since 1 newton is 0.101971621 kilogram of force then 1 kilogram of force is 9.80665 newton.

1kg (mass) exerts a force of around 9.81N in standard Earth gravity (your measured force might vary).
