First you must be aware of your assumptions. It is well known that the Egyptians measured the angle of sunlight on two wells and computed the circumference of the Earth from those measurements. The Chinese did the same thing, but they assumed the Earth was flat and computed the sun's altitude. Both got reproducible results, but one group had a false assumption. This problem comes up in everything you do.

We assume that a body in motion tends to continue in motion at a constant speed in a straight line unless acted upon by a force. We can't prove that is always true, but if it is not then the universe is run by magic and we can never know anything.

Now we hang a pendulum and watch it swing. The pendulum swings in a straight line, back and forth as the force of gravity acts upon it. We observe that the swing appears to rotate, but we insist that it swings in a straight line, so the Earth must be turning beneath it. This is called a Foucault pendulum (pronounced "foo-co").

Motion of the Earth around the sun depends even more heavily on assumptions. For a long time people thought the Earth was motionless and the planets followed complex circles. That led to a lot of inventions in geometry and clever mechanisms called "orrery". Several philosophers eventually persuaded everybody that better results were obtained by assuming that the Earth moved around the sun.

If you don't believe a concept then by definition it does not make sense. The fact is believing is seeing. Everybody who looks at the stars sees the same blobs of light. If you believe in gravity then you can see evidence of gravity at work. If you don't believe then you can not see the evidence and nobody can persuade you that it is there. This is significant because gravity is not the only theory about how the universe works. Another group says electric charge is the main factor in how the universe behaves. Both sides of this argument consider the other side to be deluded. And these are *scientists*.

So always be aware of your assumptions before you make any conclusions.

True or false Motion parallel to earths surface is vertical motion Motion parallel to earths surface is vertical motion?

False. Consider a car moving on the road, along the earth's surface. That is considered to be Vx or Horizontal motion or velocity. If the car were to move perpendicular to the earth's surface that would be Vy or Vertical motion and velocity.


What does the difference between the Earth's polar circumference and the Earth's equatorial circumference tell you about the Earth's shape?

The difference between the Earth's polar circumference and equatorial circumference, known as the flattening of the Earth, indicates that the Earth is an oblate spheroid. This means that the Earth is slightly flattened at the poles and bulges at the equator, making it not a perfect sphere.


Is earth reteograde or prograde?

Earth is considered to be prograde, meaning it orbits the Sun in the same direction as the Sun's rotation. Retrograde motion typically refers to the apparent backward motion of planets when observed from Earth, but this does not apply to Earth itself.


How many types of motion of earth?

There are so many types of motion. 10 of them are periodic motion, rolling motion, projectile motion, simple harmonic motion, rotational motion, circular motion, curvilinear motion, Oscillation, Brownian motion, and rectilinear motion.


Why are Earth's continental plates continually in motion?

Earth's continental plates are in motion due to the movement of molten rock in the Earth's mantle. This movement, known as mantle convection, transfers heat and creates the forces that push and pull the plates in different directions, causing them to move across the surface of the Earth. The continuous motion of the plates is driven by the Earth's internal heat and the resulting convection currents in the mantle.

How can you find the direction of motion from a distance x axis and time y axis graph?

To find the direction of motion from a distance x axis and time y axis graph, look at the slope of the graph. A positive slope indicates motion in the positive direction, while a negative slope indicates motion in the negative direction. A horizontal line indicates stationary motion.

The force on Earth that always opposes the motion of a body when it is in motion is called friction.
