I saw an astronaut on the shuttle lifting a piece of very heavy equipment with one hand, but they said he had to put it down very slowly, as it could still do a lot of damage. I donít understand how that could be!
There are two concepts involved here, which are very often confused. One of them is weight, which is how heavy things feel, and the other is mass. Mass can be considered as being how hard it is to accelerate or stop things. It just happens that the bigger the mass, the heavier the weight, i.e. the amount they are attracted to the Earth; this is because weight is a product of the mass and the strength of gravity.
I find the title and the content confusing. You said in the title "small mass" but in the content, it's "heavy equipment".
