Based on scientific data, the stone is accelerated at approximately 10 $m/s^2$ .

<u>Given the following data:</u>

Weight = 5 Newton

Height = 44 meters.

<h3>What is gravity?</h3>

Gravity can be defined as a force of attraction that controls the movement of the planets such as Earth around the Sun.

This ultimately implies that, gravity is a universal force of attraction that acts between all objects or matter that are having both mass and energy, and can occupy space.

<h3>Gravity on planet Earth</h3>

Furthermore, the gravity near the Earth's surface generally makes it possible for all physical objects such as stones to possess weight and experience a free fall.

According to astronomical records, the acceleration due to gravity for an object experiencing a free fall near the Earth's surface is 9.8 $m/s^2$ .

In this scenario, the stone is accelerated at approximately 10 $m/s^2$ .
