I need to calculate the damage resulting from a crash of two objects.
I found the formula of the resulting kinetic energy:
E = m * v² / 2
I guess I also have to use the masses or sizes of the objects as well.
It will make a difference if the spaceship collides with a mountain (which certainly will make both of them dealing heavy damage), or the spaceship is colliding with a floating tennisball in which case neither of them are dealing damage.
