there's a place in China where when one has to exert force to go down a slope why is this so?

It is possible that the "down slope" is only an optical illusion and in reality the slope is upwards. This optical illusion can be brought about by the surrounding features of the environment. There are at least two places here in the Philippines that I know that have the same "down slope" illusion effect. In a place called "magnetic hill", a part of Mt. Makiling, cars seems to be dragged upwards, which people thought to be caused by a strong magnetic field. But a scientific study, presented in a national physics congress, proved that the slope is actually upwards and only the surrounding made the optical illusion.

Cool and important to know!\n\nWeak soils just means earth which can't support much of a load. In some cases it is because the soil is not hard-packed. Or sometimes it is what the soil, is made from, sand, loam, peat, mud, clay, gravel, or just too much water.\n\nWhen a certain type of quake hits a weak soil, it can cause it to sort of liquefy like quick-sand. Landslides can happen on a sloping area. And anything built on it is badly damaged or partially sinks. Hey it's like building a card house on a water bed and then sitting on the edge  of the bed. Kablam! No more card house.\n\nCheck out the Google links below to see the devastation of weak soil liquefaction.

(B) At the point of a dip between two hills the force of inertia and gravity would tend to push the car down on the pavement with more force. \n(A) At the top of the hill the opposite forces would tend to make the car lighter. \n\nOf coarse several other factors would come into play like the size, speed and weight of the car, and the severity of the hills. These factors would lessen or increase the amount of force at a given point.

Drewed is basically right.  But there's more to it than that.  \n\nWhen someone says "it breaks towards the ocean", or towards the river, or even towards another town, they are referring to the topography of the area.  Basically when it rains, water runs off of the course in a certain direction (towards the ocean if you are near the ocean).  This causes certain types of grass to lay down facing the way the water runs across it, which will actually affect the way the putt rolls.  Also, of course, it is an easy way to understand which direction the hole slopes.  This won't affect the ball when its in the air though!\n\nIf you're in the desert or something, there's no ocean nearby.  For example, in La Quinta, California, the ball rolls towards the town of Indio to the East.

It comes from the fact that the "hypotenuse" of the two "triangles" is not a straight line segment.  It is actually two segments of similar, but not equal, slope.

Why would you advise anyone to jump off a short cliff? seems kinda pointless, doesnt it? In answer to your question, go to the manufactures website and try to find the instruction manual.

your acceleration moves your momentum, and you go into certain places where the forces push you down, to the side, and up. The amount of force divided by your weight is called a G-force. Rolller coasters need low G-forces to keep the rides from being dangerous, which is why most turns are on a slant: to push some of the force down instead of sideways.

If your hole is nice and air-conditioned, and you don't have to worry about incinerating in the heat of the Earth's core, then you would free fall until you got near the center, at which time you would gradually slow down due to the gravitational pull of the larger mass behind you. It's the mass of the Earth that holds you down to the ground. If you were in the dead center of it you would feel weightless because the mass would be pulling you in all directions equally. So you are heading for the other side, your velocity slowing until you would come to a stop somewhere near the surface, and then fall back into the hole going the other way, and once again slowing to a stop at the other end, repeatedly falling back and forth until air resistance brought you to a complete stop in the center, just like a swaying pendulum.

Surely the pencil will move by itself when kept on a sloping ground. But initial work had to be done to keep it at the top of the slope. You had to keep it there so that it would move downwards or you had to do work to creat the slope. That energy gets converted to the motion of the pencil.

Let me give you a chance to answer this question yourself with these two yes/no questions: Do you have to adjust your feet in order to stay in one spot for a long time (having to shuffle your feet to put them back in the correct spot as the earth moves under you?)\n\nOr has your house/appartment building ever slid off its foundation beause the earth moved under it?\n\nWhatever answer you choose, yes or no, that's the answer to your question, for the same reasons.

What i found on wikipedia- Reasons\n\nerosion by rivers, glaciers, or ocean waves create oversteepened slopes \nrock and soil slopes are weakened through saturation by snowmelt or heavy rains \nearthquakes create stresses that make weak slopes fail (see liquefaction, Hope Slide) \nvolcanic eruptions produce loose ash deposits, heavy rain, and debris flows. \nvibrations from machinery, traffic, blasting, and even thunder may trigger failure of weak slopes \nexcess weight from accumulation of rain or snow, stockpiling of rock or ore, from waste piles, or from man-made structures may stress weak slopes to failure and other structures \ngroundwater pressure acting to destabilise the slope \nin shallow soils, the removal of deep-rooted vegetation that binds the colluvium to bedrock.

The forces of erosion working to reduce its size are not keeping up with the tectonic forces involved in pushing it up, so the net result is that it is getting higher.

I would call it "shortening" and leave it at that. I know that there are thrust faults (which are low angle reverse faults) there, and that some of the pressure is released by strike-slip faulting in the Tibetan Plateau. The best term might be "Heterogeneous Strain".

Well, yes, the gavity is pulling you down, and you are not moving. So you are subjected to an acceleration and are not moving.\nMind you, one can argue that the *resulting* force is zero, as the ground is reacting with an equal and opposite force to your weight; if you take it that way, to have an unbalanced force should result in motion.

It's a ski style where the skis are like downhill skis, but the heel is detached like a cross country ski. \nThe technique is to go downhill but in a "telemark" position which is bending both knees and one foot is in front of the other... a bit like when those "flying" skiers land...\nSo the do slalom but instead of keeping both legs together they always use this position....\nNot to try in a very steep hill....

because its turning with a lot of force
