Why the acceleration due to gravity is equivalent to a constant value of /- 9.8m s2 explain?

The magnitude of the acceleration due to gravity, denoted with a lower case g, is 9.8 m/s2. This means that every second an object is in free fall, gravity will cause the velocity of the object to increase 9.8 m/s. So, after one second, the object is traveling at 9.8 m/s.

Does gravity push or pull objects towards the earth?

Why do things fall down when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. Anything that has mass also has gravity.

What is the acceleration due to gravity on Earth?

A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.

Why does gravity cause acceleration?

Gravity causes acceleration because it is a force. Remember if anywhere there is a force involved there will always be an acceleration and so is valid for gravity. The force of gravity is defined by:-F = (G*m1*m2)/d^2.

What is the acceleration of an object dropped on Earth?

An object dropped near Earth’s surface will accelerate downwards at about 9.8m s2 due to the force of gravity, regardless of size, if air resistance is minimal. Since a large object will feel a large force of gravity and a small object will feel a small force of gravity, we can’t really talk about the “force…

Why is the force of gravity constant on an object dropped?

An object dropped near Earth’s surface will accelerate downwards at about 9.8 m s2 due to the force of gravity, regardless of size, if air resistance is minimal. Since a large object will feel a large force of gravity and a small object will feel a small force of gravity, we can’t really talk about the “force of gravity” being a constant.

Why do we use the average value of gravity?

This is why we use the average value of 9.8, or sometimes 9.81. It means that any object is attracted by the earth towards its center with a Force F = m ×g, where m is the mass of the body and g acceleration due to gravity, stated in the question.
