# Whats does Origin mean?

## Whats does Origin mean?

origin, source, inception, root mean the point at which something begins its course or existence. origin applies to the things or persons from which something is ultimately derived and often to the causes operating before the thing itself comes into being.

### What does a person’s origin mean?

Origin can be viewed as the heritage, nationality group, lineage, or country of birth of the person or the person’s parents or ancestors before their arrival in the United States. People who identify their origin as Spanish, Hispanic, or Latino may be of any race.

#### What does Origin number mean?

more The starting point. On a number line it is 0. On a two-dimensional graph it is where the X axis and Y axis cross, such as on the graph here: Sometimes written as the letter O.

Where is the origin of a triangle?

The origin is the point O where all three axes intersect. This point has the coordinates 0,0,0.

What is the origin in transformation?

What is the Origin? The coordinate plane has two axes: the horizontal and vertical axes. These two axes intersect one another at a point called the origin.

## What is a 90 degree rotation about the origin?

Rotation by 90° about the origin: The rule for a rotation by 90° about the origin is (x,y)→(−y,x) .

### Are right angles 90 degrees?

Right angles are angles that are exactly 90 degrees. Obtuse angles are angles that are more than 90 degrees.

#### Is clockwise left or right?

Clockwise is spinning in the direction of an analog clock. It is a way to describe circular motion. Left or Right turns are ways of describing a change in approach. Clockwise is constantly turning to the right.

What is the rule for a rotation of 90 degrees counterclockwise?

When we rotate a figure of 90 degrees counterclockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure. Example 1 : Let F (-4, -2), G (-2, -2) and H (-3, 1) be the three vertices of a triangle.

What does a 90 degree clockwise rotation look like?

When we rotate a figure of 90 degrees clockwise, each point of the given figure has to be changed from (x, y) to (y, -x) and graph the rotated figure. Let us look at some examples to understand how 90 degree clockwise rotation can be done on a figure.

## Is a 90 degree rotation clockwise or counterclockwise?

Since the rotation is 90 degrees, you will rotating the point in a clockwise direction.

### What effect will a 90 degree clockwise rotation have on a triangle?

This rotation changes the position of the triangle (see attached diagram), doesn’t change lengths of the sides, doesn’t change angles (because the rotation is the rigid transformation).

#### What are the rules for clockwise rotations?

Terms in this set (9)

• (-y, x) 90 degree rotation counterclockwise around the origin.
• (y, -x) 90 degree rotation clockwise about the origin.
• (-x, -y) 180 degree rotation clockwise and counterclockwise about the origin.
• (-y, x) 270 degree rotation clockwise about the origin.
• (y, -x)
• (x, -y)
• (-x, y)
• (y, x)

What happens when you rotate a point 180 degrees?

180 Degree Rotation When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative.

What does it mean to rotate 180 degrees about the origin?

Rotation of a point through 180°, about the origin when a point M (h, k) is rotated about the origin O through 180° in anticlockwise or clockwise direction, it takes the new position M’ (-h, -k). …

## Is the earth rotating?

The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly 1,000 miles per hour.

### Why don’t we fly off the earth?

Normally, humans aren’t thrown off the moving Earth because gravity is holding us down. However, because we are rotating with the Earth, a ‘centrifugal force’ pushes us outwards from the centre of the planet. It is greatest at the equator and zero at the Earth’s poles.

#### Will the earth ever stop spinning?

Earth isn’t likely to ever get tidally locked to the sun — we’re too far away for that to happen. And, though our planet’s rotation is slowing down ever so slightly (a day gets about 1.7 milliseconds longer every century), our planet should never stop spinning completely.

Why can’t you see the earth spinning from space?

You don’t see the earth spinning from earth because it spins at 360 degrees per day. It’s just too slow for you to notice.

Can a plane fly faster than the Earth rotates?

At the equator, the Earth spins about twice as fast as a commercial jet can fly. That rate slows the closer you get to the poles, but regardless, it’s always going to be faster than a plane.

## Why does the moon never rotate?

Gravity from Earth pulls on the closest tidal bulge, trying to keep it aligned. This creates tidal friction that slows the moon’s rotation.

### What would happen if Earth stopped spinning?

If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth’s original 1100 mile per hour rotation speed at the equator. This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere.

#### What would happen if the Earth stopped spinning for 1 second?

At the Equator, the earth’s rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
