# Jessie Johnson - EARTH, MOON, SUN and Centri-petal Force. Flat Earth Truth - DEBUNK - here is why you don't fly off the Earth due to its rotation

Hi Jessie,

The bottom line is that your Earth to Earth, Earth to Moon, and Sun to Earth METHOD of calculation is wrong. **Your method does not properly take into account circular motion**

You are not using the correct procedure or formula to calculate Centripetal/Centrifugal Force.

Definition:**Centripetal force** - the component of force acting on a body in curvilinear motion that is directed toward the center of curvature or axis of rotation**Centrifugal force** - an apparent force that acts outward on a body moving around a center, arising from the body's inertia. **It is equal and opposite in value to the centripetal force**

Use any three of the following variations for Centrifugal force calculations...

Use this calculator (http://www.calctool.org/CALC/phys/newtonian/centrifugal) to compute the Earth's centrifugal force on an object at the Earth's equator.

Radius = 3,959 miles

Linear speed = 1,040 miles per hour

Angular speed = 15- degrees per hour

Mass = 1 Earth

- - - - - - - - - - -

Result:

Centrifigal acceleration = 0.00343594 of the value of g (which is 9.8 m/sec/sec), OR **0.34 PERCENT of the g****So the centrifugal throw off acceleration from the Earth's surface = 0.00344 = 0.345 percent of the gravitation attraction of you already. **

That force at the equator is enough to make you weigh 0.4 grams less, than at the Earth's poles.

That is why we are not thrown off the Earth's surface.

Centrifugal force = 2.01281e+23 newtons (kg * m/s/s/), OR 201,281,000,000,000,000,000,000 newtons

I'm sorry to tell you but some of your conclusion calcs are incorrect. You still are confused between weight, mass, velocity, linear verses angular momentum, centripetal force, and force in general

The misunderstanding presented on this page...

You are mixing up force-pound verses weight-pounds

*

WEIGHT to MASS conversion, on the Earth because gravity at 9.8 m/ses/sec is already figured in

1 pound in weight = 4.45 newton earth (N) = this is now mass, how much matter there is in something.

*

Now here we are dealing with FORCE.

Force = mass * acceleration

1 newton meter = .225 lbs force

lbs or pound-force is a force unit of measure.

1 newton equals .225 pounds because .1020 kg of mass accelerated at 9.8 m/s sq equals a newton and I can easily convert the force of kg mass into pound force since 1kg mass= 1kg mass force at gravity on earth.

So this is based on being on the Earth's surface where the gravitational force is included.

1 pound-force = 4.4482216152605 newtons of force

1 pound-force = 444822 dynes

1 dyne = a unit of force that, acting on a mass of one gram, increases its velocity by one centimeter per second every second along the direction that it acts.

1 dyne centimeter (dyn cm) = 0.000000074 pound force feet (lbf ft)

At average gravity on Earth (conventionally, g = 9.80665 m/s/s), a kilogram mass exerts a force of about 9.8 newtons, due to the force of gravity that is already acting on it.

Note: pds is not a valid unit of measure.

*

VELOCITY in the field of gravity. **Velocity DOES NOT DEPEND ON MASS**. All fall at the same accleration rate of (g = 9.80665 m/s/s)

Dropped from a height on 100-meters, an object will fall for 4.51 seconds before hitting the earth, and will at that time be traveling at 44.27 m/s

For a 1 kg object, the force of impact on the ground = 9,800 newtons.

For a 5 kg object, the force of impact on the ground = 49,900 newtons

For a 25 kg object, the force of impact on the ground = 245,000 newtons

For a 80 kg object, the force of impact on the ground = 784,000 newtons**Impact velocity (44.27 m/s) is the SAME for all of these different weight objects**

Dropped from a height on 1,000-meters, an object will fall for 14.28 seconds before hitting the earth, and will at that time be traveling at 140 m/s

For a 1 kg object, the force of impact on the ground = 98,000 newtons.

For a 5 kg object, the force of impact on the ground = 490,000 newtons

For a 25 kg object, the force of impact on the ground = 2,450,000 newtons

For a 80 kg object, the force of impact on the ground = 7,840,000 newtons

Energy at splat time: 1/2 * mass * velocity^{2 }= mass * g * height

Impact force from falling object (http://hyperphysics.phy-astr.gsu.edu/hbase/flobi.html)

*

1 pound-force (which is not 1 pound of weight). It’s a measurement of force (lbf). Should not be confused with foot-pounds or pound-feet.

Weight and mass conversion – on the surface of the Earth

1 newton earth (N) in mass = 0.22 pounds (lbs) BUT, this is because g = 9.8 m/sec/sec, and that's already in the calculation.

W = mg

This conversion calc is wrong

2.2 pds = 2.2 X 4.445 newtons = 9.8 newtons

pds here is weight.

*

F = m * a

1 newton = 1 kg * 1 m/sec/sec

F = ma is force

The pound-force is equal to a mass of one avoirdupois¹ pound multiplied by the standard acceleration due to gravity on Earth, which is defined as exactly 9.80665 meter per second². Then one (1) pound-force is equal to 0.45359237 kg × 9.80665 meter per second² = 32.17405 pound × foot per second²).

The bottom conclusion math presented on this page is just flat out wrong

That is not the correct representation of centrifugal force.

Momentum is mass in motion.

Linear momentun = mass * velocity, or p=mv

Linear momentum unit of measure:

If the mass is in kilograms and the velocity in meters per second then the momentum is in kilogram meters/second (kg m/s).

*

The angular momentum, L of a rigid body with moment of inertia I rotating with angular velocity is: L = I. This is the rotational analogue of linear momentum.

Note: The units of angular momentum are - kg m^{2}/s.

The angular momentum, L of a rigid body with moment of inertia I rotating with angular velocity is: *L* = *Iw*.

Update December 27, 2017 - Jesse Johnson has since deleted the following two comments to hide our information from his subscribers. If he was really 100% confident about the numbers presented in his video, there should have been no need for this.

He just want's to make sure that his subscribers remain in the dark, commited to him.

Summary - your calcs and interpretation of the physics involved is wrong. Please take a university level physics 101 class.
