When the moon faces earth a solar eclipse happens :-)
<span>So we want to know which Newtons law explains the reaction when we bump into the coffee cup the coffee is spilled out. So Newtons 1st law says that a body stays in motion or it stands still until a force acts on that body. So we acted by a force on the coffee cup and the coffee continued to move even if there was no force on the coffee after we bumped the coffee cup.</span>
Mass: the amount of matter an object contains
Weight: mass•acceleration due to gravity(9.8m/s) / the force of gravity acting on an object
