Learn the difference between potential energy which is stored energy and kinetic energy which is the energy of motion. In this video, I compare gravitational potential energy to kinetic energy. I also review the formula for potential energy and the formula for kinetic energy.

Bill Gates has a net worth of around 93,000,000,000 dollars.
This is a large number to write.
A nanometer is 1/ billionth of a meter which is written as 0.000000001 m

Both of these numbers can be written using scientific notation.
Bill Gates net worth could be written as 9.3 x 10^10
A nanometer can be written as 1.0 x 10^-9
Lets go over the basics of scientific notation

9.3 x 10^8
The coefficient must be between 1 and 10
The exponent should be an integer and can be positive of negative

If you have to move the decimal to the left , the exponent will be positive
If you have to move the decimal to the right the exponent will be negative

530,000 5.3×10^5
First example. In this example we do not have a decimal so you can assume it is after the last zero. The coefficient must be between 1 and 10 so we need to move the decimal five places to the left because 5.3 is between 1 and 10
The exponent will be positive so it will be written as 5.3 x 10 5

.00078 x 10^-4

In this example in order for the coefficient to be between 1 and 10 we need to move the decimal four places to the right 7.8 is between 1 and 10
We need to move the decimal to the right so the exponent will be negative

The scientific notation will equal 7.8 x 10^ -4

x-linked inheritance and male pattern baldness.
An x-linked trait which is a sex linked trait is a trait found on the x chromosome.
Females have two x chromosomes and males have an x and a y chromosome.
The x chromosome has almost 800 genes compared to only around 70 found on the y chromosome.

Let’s look at the Punnett Square for another x-linked disease, hemophilia
In this example, the father has the disease and the mother is a carrier.
With a recessive x-linked disease a female can be a carrier
Have the disease, or not have the disease.
Males can only have the disease or not.
Let’s go back to the Punnett square and their offspring.
This female is a carrier, this female has the disease, this male has not inherited the disease and this male has hemophilia.
Notice the Punnett square works similar to a monohybrid cross except the y is neither dominant or recessive. I will call the y chromosome neutral
Because males either have the disease or not, they have a greater chance of inheriting an x-linked trait.
So there you go, traits found on the x chromosome.

Divergent plate boundaries occur when two tectonic plates move away from one another.
Divergent plate boundaries are considered constructive boundaries.
If you look at a map of the major tectonic plates you can see several divergent plate boundaries.
There are two major types of divergent boundaries.
Continental and continental lithosphere and oceanic and oceanic lithosphere.
An example of an oceanic and oceanic divergent boundary is the mid-ocean ridge.
The mid-ocean ridge runs around the world including going right through Ice land.
A famous example of a continental and continental divergent boundary is the African rift valley.

Difference between angiosperm and gymnosperm plants.
Angiosperms are flowering plants.
Their seeds are enclosed in a protective covering called fruit.
Gymnosperms have a naked seed and many are cone bearing trees.

As the moon rotates around the earth it travels through phases.
The alignment of the sun, earth, and moon create the phases.
I use an orrery to explain the moon's alignment during,
new moon, waxing crescent, ist quarter, waxing gibbous, full moon, waning gibbous, last quarter, waning crescent, and back to new moon.
The sidereal period is 27.3 and the moon is measured against stars.
The synodic period is 29.5 days and the moon is measured against the sun.

Gravity depends on mass and distance and is an attraction between objects with mass.

Why does the same side of the moon always face the earth?
Because of the orbit of the moon and its rotation are almost the same the near side of the moon always faces the earth. The orbit of the moon is elliptical and has a slight tilt.
