Question

Two objects are dropped from the third floor of the building and one of the object is having three times more mass than the other which will fall first if there is no air resistance justify

Answer 1

These two objects clearly have different mass but they fall with the same acceleration. I guess I should point out one more thing about falling objects. If you were to measure the position of these balls as they fall, they do not fall with a constant speed. Instead, they fall with a constant acceleration. That is to say that as they fall, the speed increases. For these two objects, they hit the ground at the same time because they both start from rest and both have the same acceleration.


This was the reason for Galileo's experiment .

But the above fact ignores the fact that each of the two objects are attracting each other. In particular, the heavier object also attracts the lighter object, thus decreasing the distance between the lighter object and earth.
Note : I am ignoring the fact that the lighter object would also attract the heavier object (but to a lesser extent) and since the earth moves approximately in the same direction as a result of the attraction from the other two spheres, that is also ignored. Otherwise the earth can be said to move diagonally towards the heavier object (again to a small extent).

Answer 2

Answer:

Explanation:

hey here is your answer...........

when a body covers equal distances in equal interval of time then it is said uniform motion

when a body cover unequal distances in equal interval of time then it is said to be non uniform motion.
