Acceleration of Gravity
The rate of change of velocity due to net force on an object is known as acceleration. There is a force on Earth which we can always depend on is the omnipresent gravity force which helps in pulling down any objects which has mass.
The magnitude of Acceleration of Gravity on Earth is 9.8m/s2 down toward the centre of the Earth which can be taken as 10 m/s2. It means if the Acceleration due to Gravity is going to be the only force acting on an object placed on Earth, then the object will be found to accelerate at a constant rate of 9.8m/s2.
Therefore any object will always fall at this rate but the air act to slow them down. For example; if we drop a grape and a grapefruit at the same time from the same height, they will reach at the same time. But if we drop a book and a piece of paper, the paper of the book is not found to accelerate as much as the book.
I like to share this Linear Accelerator with you all through my article.
This is because; in the case of paper, a small force of gravity is opposed by the force of air friction while a similar kind of force would be acting on the book from the air but small compared to the force of gravity on it.
Overall in the absence of a proper or relevant amount of wind, all things would fall downward with same acceleration as there is no friction. Remember; the value of 9.8m/s2 is acceleration not gravity which is a force of attraction. This represents by “g” or “a gravity”
The value of ‘g’ varies from one celestial body to another. For example, the value of ‘g’ on the Moon is 162.4 cm/s2 or 5.847 km/h/s or 5.328 ft/s2 which are different from the value of ‘g’ at Jupiter
