on an object from a distance. That’s the reason they are non-contact forces. The strength of gravity is an attractive force that is exerted by the Earth on objects, which makes them fall to the land. The weight of a body is the force that is pulled by the earth towards the centre...
The meaning of FORCE is strength or energy exerted or brought to bear : cause of motion or change : active power. How to use force in a sentence. Synonym Discussion of Force.
[translate] aHe proved that force exerted by an object in motion is proportional to mass times acceleration. 他证明,一个对象施加的力量在行动与许多时期加速度是比例。 [translate] 英语翻译 日语翻译 韩语翻译 德语翻译 法语翻译 俄语翻译 阿拉伯语翻译 西班牙语翻译 葡萄牙语翻译 意大利语翻译 荷兰语翻译 ...
Gravity - Newton's Law, Universal Force, Mass Attraction: Newton discovered the relationship between the motion of the Moon and the motion of a body falling freely on Earth. By his dynamical and gravitational theories, he explained Kepler’s laws and est

In this study, we used optical tweezers to measure the force exerted by filopodia and lamellipodia with a millisecond temporal resolution. We found that a single filopodium exerts a force not exceeding 3 pN, whereas lamellipodia can exert a force up to 20 pN. Using metabolic inhibitors, we ...
By knowing the force of gravity on an object and its mass, we can use the equation to calculate its acceleration toward the ground.The force equation is also used to study the behavior of fluids and gases. For example, when air flows over an airplane wing, it creates a force that lifts...
The force exerted by an electric charge at the origin on a charged particle at a point (x,y,z) with position vector = x,y,z is ()=(K)(||^3) where K is a constant. Find the work done as the particle moves along a straight line from (2,0,0) to (2,1,5). 相关知识点:...
The force exerted by unbroken surface waves on a cylindrical object, such as a pile, which extends from the bottom upward above the wave crest, is made up of two components, namely: 1. A drag force proportional to the square of the velocity which may be represented by a drag coefficient...
Electric phenomena occur even in neutral matter because the forces act on the individual chargedconstituents. The electric force in particular is responsible for most of the physical and chemical properties ofatomsandmolecules. It is enormously strong compared withgravity. For example, the absence of ...
