hi, thank you for helping
For same momentum change if we increase the time of impact by factor ten then force is smaller by factor ten.
But why is that? I mean why doesn't a moving object at point of impact give away all of its momentum at the instant it hits something,no matter if that something is a wall or a ball or a piece of paper?
when two objects collide any combination of force and time could be used to produce certain impulse. What are the parameters that decide ( for specific impulse ) the amount of force two object colliding will exert on each other and the amount of time collision will last?
If two balls with same mass and speed go towards each other then momentum is zero. When they colide they both lose momentum, so how can they claim if one object loses momentum then the other object gains momentum?
I see that being true if both objects are moving in same direction or one is still. In that case one object would loose while other would gain momentum
cheers
