While centripetal force is an actual force, centrifugal force is an apparent force. In other words, when you twirl a rock tied on a string, the string exerts an inward centripetal force on the rock, while from the rock's point of view, there appears to be an outward centrifugal force on...
Stop quoting old clever people and become one yourself. We need to move on. When the so called experts say the object should go straight out if there is such a thing as centrifugal force, they seem to forget that it is being driven by the g: string in a direction as well as held ...
a seat on a swing), the centripetal and centrifugal are equal in magnitude, but opposite in direction. The centripetal force acts on the body in motion, while the centrifugal force does not. For this reason, centrifugal force is sometimes called a "virtual" force. ...
How is G-force used to monitor risky driving behaviours? A question we get asked frequently is: “How do g-force values relate to real world driving habits?” In fleet management software like MyGeotab, harsh driving — when accelerating, cornering or braking, for example — is defined in ...
The steeper the slope is, the more powerful this force becomes. It’s also worth noting that going uphill will increase your speed reading even when moving at the same speed as you would on an equal downhill slope. City Driving The D mode is for driving on the highway; the D3 mode ...
The input is connected to the engine crankshaft. The output can drive a chain, belt or shaft. As the rotations per minute increase, weighted arms swing out and force the clutch to engage. Centrifugal clutches are also often found in lawn mowers, go-karts, mopeds and mini-bikes. Even some...
It is slightly weaker at the equator due to the centrifugal force caused by Earth's rotation and the fact that the Earth is not a perfect sphere but an oblate spheroid. Gravity is stronger at the poles and weaker at higher altitudes. This variation is why your weight can change slightly ...
The overall force to which a structure is subjected in supporting a weight or mass or in resisting externally applied forces. Force Power made operative against resistance; exertion Use force in driving a nail. Load Something that is carried, as by a vehicle, person, or animal A load of fir...
Force The capacity to do work or cause physical change; energy, strength, or active power The force of an explosion. Strength The capacity to resist strain or stress; durability The strength of the cables. Force Power made operative against resistance; exertion Use force in driving a nail. St...
蚜虫有很多分类。有的蚜虫喜欢蔬菜，有的蚜虫喜欢水果，有的蚜虫喜欢棉花，于是就有了麦蚜、苹果蚜、桃蚜、甘蓝蚜、棉蚜等。在长期的协同演化中，每种蚜虫形成了不同的寄主生物型以适应不同的寄主植物，以至于不同蚜虫互相之间出现了明显的差异，例如苹果蚜跟苹果在一起久了，对玉米的适应能力就变得很差。 根....
