Motion Under Gravity

Gravity, described as acting by Isaac Newton, is the force that brings things with mass towards each other. Here on Earth, gravity gives an impressive force that pushes everything away from its centre, resulting in, for instance, falling objects and throwing projectiles. Understanding the nature of satellites’ motion under gravity assuming gravitational acceleration and determination of future orbits is very critical.

An item that experiences a change in motion which is in vertical motion due to the gravitational force is known as motion under gravity. GRAVITY is an ordinary yet powerful force which makes things move down in a free fall.

Acceleration Due to Gravity

The gravitational acceleration is the objects’ rate at which they have been accelerating towards the Earth due to the gravitational force. Somewhere near the ground, as one approaches the Earth’s surface, this acceleration is approximately 9.8 m/s^2. The latter statement implies that in every second, what falls significantly increases its velocity by 9.8 m/s in the direction of fall. The gravitational acceleration is rather a constant value near the Earth’s surface while it may change with altitude or with the location just a bit. This is because it plays a central role in the application of this theory to diverse areas such as free fall and projectile motion.

Gravitational acceleration is typically denoted by the symbol g, and its formula is:

g = W/m

where,

• g is Gravitational Acceleration
• W is Force of Gravity Acting on Object
• m is Mass of Object

Gravitational acceleration is approximately 9.8m/s².

Motion under gravity is the motion of an object moving under the influence of gravity. gravity is the constant pull of Earth’s surface that pulls every object to its centre. The motion of a fruit falling from the branch of the tree is considered motion under gravity.

In this article, we will learn about Motion under gravity, Equation of motion under gravity and others in detail.
