Newton's universal law of gravitation states that all objects attract each other with a force directly proportional to their masses and inversely proportional to the square of the distance between their centers. When considering objects on the surface of the Earth, the force is directly proportional to the product of the mass of the object and the acceleration due to gravity at the Earth's surface. Since the Earth is larger than any other object under consideration, the object is drawn toward the Earth.
Explanation:
The magnitude of the gravitational force between two objects is given by Newton's universal law of gravitation:
where :
is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between them
This force is always attractive.
At the Earth's surface, this can be rewritten as
with
where M is the mass of the Earth, R is its radius, and m the mass of the object.
g is called acceleration due to gravity and it is the value of the acceleration due to the force of gravity of any object near the Earth's surface (its value is approximately . Since the Earth is much more massive than any other object, the object is attracted towards the Earth (so, it accelerates towards it); the Earth is also attracted by the object, however, being its mass so large, its acceleration is negligible.

Livestock producers and breeders rank livestock on their ability to produce high quality, efficient breeding animals and market-worthy <u>offspring</u>.
To be able to effectively evaluate breeding and market animals is of vital economic importance for the animal markets. The same traits used to evaluate <u>high-grade slaughter animals</u> are also important in the <u>grading </u>of <u>breeding stock</u>.
When we judge livestock we classify them as:
- Superior livestock
- Average livestock
- Inferior livestock
We are looking for the most desirable traits to fit our particular market and genetic needs. The "Livestock Judging Manual" indicates that some of the most prevalent traits necessary to score a better rating are:
- <em>Live weight</em>
- <em>Fat depth</em>
- Muscling
and many more. The most important of which is muscling given that an animal with more muscle will produce more desirable meat for the average consumer, and therefore can be sold at higher prices.
