Question

Why does a heavier object hit the ground first?

Answer 1

Hint:Before going to solve the questions let’s understand some terms. Gravity is defined as the force between an object and the earth’s surface. It depends on the mass of the object and the distance between the object and the gravity source. Gravity exists everywhere in the universe and it is the most important force and also it is the weakest force.

Complete step by step solution:
Gravity has a higher effect on a heavier object to pull harder than the lighter one in order to speed them both up by the same amount. But, in the real world, we have air resistance, which is why sometimes heavier objects do fall faster than lighter ones. On earth according to Newton's law of gravitation, every object will attract another object.

In order to understand this, we will go through this example once. Consider an iron ball and a plastic ball dropped from the same height, then they both will not fall at the same speed. Due to the external effect like the air resistance on gravity, it seems that the iron rod falls at a greater speed. As we know that the force F is directly proportional to mass m. As long as the mass increases gravitational force also increases.

Note:Think that, suppose if we drop an iron ball and a plastic ball in a vacuum, then because there is no air resistance in the vacuum, they both might fall at the same time.
