Why is gravity an example of scientific law?

Answers

Answer 1

Answer: Gravity can be an example of scientific law because of the fact that it has been proven over and over, again and again. While a theory is proven by evidence, it can be disproved. Laws rarely change. Although there are theories about gravity as well. The difference is a theory explains why it happens while a law lets us calculate a way to find what happened. In Newton's Law of Universal Gravitation, the formula will allow you to calculate the gravitational pull of the Earth and what ever you dropped for instance. However Einstein's Theory of General Relativity explains why whatever you dropped fell. So it depends what you mean by gravity being a law. It can be both depending on if your using it to prove something or to explain why that force occurs. :)

Answer 2

Answer:

Because it is a basic concept that defines a constant and universal behaviour of nature, gravity is seen as an illustration of a scientific law.

Scientific laws are succinct formulations that precisely explain a natural occurrence and are the result of in-depth observation and investigation. Einstein's theory of general relativity or Newton's law of universal gravitation both use the concept of gravity to explain how mass-containing objects interact with one another in space.

It offers a mathematical framework that enables researchers to perform precise projections and estimates about celestial body motion, the behaviour of things close to the surface of the Earth, and the structure of the cosmos.

The fact that gravity is recognised as a scientific rule is a reflection of the fact that it is widely accepted and has been shown to have practical applications.

A football is kicked with a velocity of 18 m/s at an angle of 20. What is the balls acceleration in the horizontal direction as it flies through the air

Answers

If we perform all of our experiments on Earth and ignore
air resistance, then vertical acceleration is always 9.8 m/s²
downward, and horizontal acceleration is always zero.

My apex test just corrected my original answer of 9.8 m/s^2 to 0 m/s^2.

What is the total displacement of a bee that flies 2 meters east, 5 meters north, and 3 meters east? explain how you did it

Answers

The displacement covered by the bee that flies 2 meters east, 3 meters east, and 5 meters north is 7.05 meters.

What is Displacement?

Displacement of an object can be defined as the actual change in the position of an object. It is a vector quantity because it has both the direction and the magnitude.

The bee travels 2 meter east and 3 meters east. Therefore, the total distance covered in the east direction is (2+3) meters = 5 meters.

The bee travels 5 meters in the north direction. This makes a square of 5 meters dimension and in this condition, the displacement covered by the bee will be the diagonal of the square. Therefore, the total displacement of the bee can be calculated as:

Diagonal of square = $√(2)$ a

where, a = side of the square

Side of the square = 5 meters

Diagonal of the square = $√(2)$ × 5

$√(2)$ = 1.41

Therefore, diagonal = 1.41 × 5

Displacement of the bee = 7.05 meters

It flies 2+3meters east and 5 meters north so it flies 5 east and 5 north. Then the way of it would be diagonal of 5x5 square it equals 5√2 which is 7.07.

Answers

A stack or sea stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion. Stacks are formed over time by wind and water, processes of coastal geomorphology.

It is called a Sea Stack.
