Thus if you know the mass of the object, you can use algebra to solve for the velocity v by setting _EP (initial) to EK_ at "launch." We can describe the total mechanical energy of such a situation as the sum of kinetic and potential energy. References Stanford...
Describing a Force:A force is a vector quantity. A vector quantity is a quantity which has both magnitude and direction. To fully describe the force acting upon an object, you must describe both its magnitude and direction. Thus, 10 Newtons of force is not a complete description of the ...
No one can say exactly what gravity "is," but it is possible to describe it mathematically and in terms of other physical quantities and properties. Gravity is one of the four fundamental forces in nature, the others being the strong and weak nuclear forces (which operate at the intra-atomi...
How to find distance using force and acceleration? Determine the magnitude of the resultant force. What is the force? What is the dimensional formula of force? What is the dimensional formula of the force? What is pseudo force? Give 10 examples of force and briefly describe each force there...
1. Is there anything from your first interview you'd like to revisit? 2. How would you describe yourself? 3. Why do you want to work for us? 4. Why should we hire you? 5. Describe your ideal job. 6. Where do you see yourself in 5 years? 7. What kind of work environment...
How do you describe the surface of one thing? Round? Square? Or smooth? You may have different answers. But we know that we can describe the earth’s surface through landforms (地形). A landform is a natural mixture of rock and soil found on the earth. Landforms come in different kinds...
An anecdote is a brief account of events that lacks the complete structure of a story. It might describe a moment at work or a fun experience at an amusement park but doesn’t necessarily include all five key story elements. When I was young, my grandfather took me to the park to feed...
14. How do you describe the direction of the weight and normal force? D A. The two have the same direction. B. The magnitude of these two forces is always equal. C. The two are always in the completely opposite direction. D. The two have different directions regardless of the surface...
Whereas the extent of these conformational changes has been correlated to the level of TCR–pMHC catch bonds4,6,22, the two have not been integrated into a mathematical model to explore their potential connection. Here we develop two such models, one for each MHC class, to describe both α...
So, if we have to live with stress, we may as well find out more about what it is, how we can deal with it and so on. 所以,既然我们不得不忍受压力,不妨多了解它是什么,我们该如何处理它,等等。 What is stress, then? The term was originally used in physics to describe the force exer...
