Answer on Mechanics | Relativity Question for Saad zubair
According to Galileo if we drop two objects of different masses from a height both will reach the ground at same time because the value of gravity which pulls them downward is same. Now the definition of weight is this that " weight is that force with which earth attracts a body towards it's centre" now the question is that if the weight of one object is heavier than other so there will be greater force in that object if the force is greater than motion will increase and the objectwill reach the groun earlierly so concept of Galileo is getting wrong according to this definition.
According to Newton's second law: F=ma hence a=F/m Acceleration is equal to force divided into weight of an object. Gravity acceleration does not depend on weight of an object and both objects will fall simultaneously
