Hello everyone! Today, I will continue to give you a question about the properties of energy Good and difficult And it is also at the level of too light It's not too difficult for you to think This is a question from the science of science If you are in the science of science, you will participate in many questions like this And even better and more difficult This question is evaluated at the level of the basics in the science of science The answer is as follows 1. There is a spring that is placed at the location of G by Pi The unit is the meter on the spring, which is about 10 2. It is stimulated by the harmonic motion in a straight line 3. The property of momentum according to the deformation of the spring As shown in the figure Find the speed of the object when the deformation is A A is a position on the screen At this time, our momentum is 3 over 4 of the magnetic field Magnetic field is 4 parts At this time, the momentum is 3 over 4 of the magnetic field I will explore later I will explore the data of this object This is a very important point At this point, the momentum is 0 And the degree of deformation is 1 At this point, the momentum is 0 That position is 0 Our momentum is only at the edge But what edge is it? Pay attention With a spring hanging straight There will be two states The point and the edge The distance between the two states is at the natural position The degree of deformation is 0 It is the boundary between the point and the edge Let's look at this point This point is like a circle The degree of deformation is 0 This is the natural position The boundary between the point and the edge You know With a spring hanging straight The direction of the edge will be more The direction of the point The time of the edge will be more Look at this This is the boundary The upper part The boundary over there It will be the time of the spring The whole process from here to here is the spring At this point, the spring is the most At this point, the spring is not deformed At this point, the spring is the most It is at the natural position The momentum is 0 This position is 0 The degree of deformation is 1 The momentum is 0 It is at the edge We have just proven that the most It is at the natural position The degree of deformation is 1 This is the most deformed degree At the edge It is the most It is A minus delta L0 Delta L0 is the degree of deformation At the equilibrium position Here Ok The deformation at the edge It is A minus delta L0 It is the most deformed The unit is cm I have a formula A and delta L0 Next Let's use another position This position on the screen Right This position The degree of deformation is 0 It is at the position The degree of deformation is 0 It is at the natural position Right There At the natural position What does the equation give you? The momentum at this time is 3 quarters of I'm sorry 1 quarter of the extreme The momentum is 1 part The momentum is 3 parts At this position Our momentum is 1 quarter of the extreme The momentum is 3 quarters of the momentum Right When the momentum is 3 quarters of the momentum Our x What do you think? Plus minus acan3 over 2 Specifically, it is a minus sign Because at the natural position It is a negative position with a downward slope Right At this time, our x is minus acan3 over 2 Done Because the momentum is 3 quarters of the momentum And at the natural position Our x is minus delta L0 It has always been At the natural position The degree of deformation is minus delta L0 So you can get here We get Our A Delta L0 Right Delta L0 With acan3 over 2 Done From the upper equation and the lower equation Right What will I get? I will get A and delta L0 This is a pretty good sentence By A teacher Admin It's pretty good Right You know, Mr. Huy Tai I made a pretty good sentence the other day And Mr. Tran Vinh Today is Mr. Huy Tai's friend I made a pretty good sentence about this Right There are a lot of teachers in my department Admin channel Good And A lot of creativity It was my old student In the past I made a lot of good sentences So I hope that After these videos We can Have a good idea You can send it to me Right I will fix it and read your name Very proud Right Already Continue to repair I will get here What is this? Um Delta L0 and A Are there two hidden equations? I replace this number 1 keep the original Our A Is 2 delta L0 There Divide by 3 And here Directly for Delta L0 Done? Come on Press delta L0 1 Divide by 2 parts of 3 Divided by 1 Right Ok Our delta L0 Here Um It is equal to 6.46
