Why the center of pressure is below the center of gravity for an inclined surface?

I'm going to guess it's for easier guidance. If center of pressure were above CG, you'd blast your rocket so that's out, we're not pulling here, we're pushing. If CP is below but too close to CG, you would have a balancing issue. Try to balance a tall object such as a broom on your hand. It's much easier to do than balancing a short object such as a pen. Easier to correct and stay under CG, with more distance.

∙ 8y agoI am not entirely sure about the details, but the question seems to imply that the object is in balance; and I would think that if the center of pressure is anywhere else, the object would not be balanced.

What is the center of gravity of truck when its on inclined position?
The position of an object has no effect on the location of its center of gravity. It may have an effect on the truck's center of gravity, however, if the truck's load shifts on the incline. But that's the result of an actual shift in the center of gravity, not the result of the incline.
What is the difference between the 'center of gravity' and the 'center of pressure'?
None
What is the scientific definition of gravity?
Gravity: The attraction between an object on the surface and the center of the earth.
Do the center of mass and the center of gravity coincide?
Yes . If the center of pressure, for the vehicle as a whole, is not located behind the center of gravity (away from the direction of the flight path), then the vehicle will have unstable motion and can tumble. Adding fins to the rear of the vehicle (or increasing fin surface area) will move the center of pressure aft, affording stable flight. A similar effect can be produced by adding weight to the front of the vehicle.
What is the accelaration gravity of the center of Earth Surface?
At the earth's center, the acceleration/force of gravity is theoretically zero.(At least the force of gravity between the earth and an object at its center. There's still the gravitational forcesbetween the object and everything else ... the sun, moon, stars, etc.)
Applications of center of pressure?
As the intensity of pressure increases with depth so for an inclined surface CP is bellow CG. Center of gravity : a point from which the weight of a body or system may be considered to act. In uniform gravity it is the same as the center of mass.
How does the pressure change as you go from the surface towards the center of the Earth's?
the pressure changes by how deep you are below see level because of gravity?
What has more pressure the center or surface of the earth?
The center, because that is where all the gravity of Earth pulls you down(this is why when you jump you come down) create lots of friction and pressure
Center of pressure on an inclined plane is?
below the centroid
Why center of pressure is below center of gravity?
I assume you are talking about a model rocket. Center of pressure needs to be below center of gravity in order for the rocket to fly straight. Mathematically, the rocket will tilt around the center of gravity but appear to be pushed from the center of pressure, hence the need for the center of pressure to be below the center of gravity, otherwise the rocket will just corkscrew off the pad. The fins move the center of pressure down.

How does pressure changes as you go from the surface to the center of the earth?
As you travel from the surface to the center of the Earth, pressure will increase enormously, because of the increasing weight of what is above you.
Is earth's gravity the same on the surface as it is in the center of the earth?
No. At the centre of the earth the acceleration due to gravity is ZERO
What is Neptune's Gravity compare to Earth Gravity?
Neptune has 17 times the mass of Earth, but it is also larger, and gravity diminishes the farther you are from the center of gravity. So, if it had a solid surface, Neptune's surface gravity would only be slightly higher than Earth's (14% greater or 1.14 G). The gravitational acceleration at the point where its atmospheric pressure is equal to Earth's at sea level is 11.15 meters per second squared.The pull of gravity on the surface a planet or moon depends on two things:The mass of the planet or moon.How far its surface is from the center of gravity.The related links include a good website that shows you the comparison between the pull of gravity (how much you would weigh) on the surface of all the planets.
What rises to the surface and may create a volcanic center?
