HT OF A FREELY FALLING BODY:

What is the weight of a freely falling body.

When an object of mass m falls freely, the downwardacceleration of gravity. The apparent weight of a freethe object acts as if it were weightless in the universe attracts every other material baional to the product of their masses and inversof the distance between them, and isdirected alot a moment
