ContentsThus when you jump from a moving bus your body wants to keep moving with the same velocity as that of bus bur the moment you lay your feet on ground friction starts acting which opposes your motion.In simple words,newtons first law and friction will play a nasty role and give you unwanted results if you try to jump from a moving bus. [6] Secondly, >>Why is it dangerous to jump... Question Why is it dangerous to jump out of a moving bus? Easy Open in App Solution Verified by Toppr While jumping from a moving bus, our feet comes to rest on touching the ground, whereas the upper part of our body continues to move forward due to inertia of motion. [5] Simply so, What is the difference between jumping on top of a bus? The only difference is that when you are on top of the bus, there is air pressure (aka wind) blowing in your face. If bus is moving at 60 mph, there is a 60 mph wind, which is quite strong. So, when you jump, this wind tends to push you back. If there was no air resistance, then your jumps inside and outside would be equally uneventful. [6] Do you move relative to the direction the bus is moving? You do not move relative to the direction that the bus is moving -- you and the bus have a constant velocity in that direction. The combined linear momentum of you and the bus in the direction of travel does not change as you jump straight up relative to the bus. Thanks for replying so quickly! [6] Similarly, What is the inertia of the man jumping out from the bus? The man jumping out from a moving bus holds the inertia of motion. Hence the person may fall forward from moving bus if tries to jump because our body was in movement. A man jumping out from a moving bus holds the inertia of motion. [8] Do you move relative to the direction the bus is moving?Beside above, What happens when you jump straight up relative to a bus? The combined linear momentum of you and the bus in the direction of travel does not change as you jump straight up relative to the bus. Thanks for replying so quickly! So you don't move relative to the bus? [6] Additionally, How do you move relative to the direction of a bus? You do not move relative to the direction that the bus is moving -- you and the bus have a constant velocity in that direction. The combined linear momentum of you and the bus in the direction of travel does not change as you jump straight up relative to the bus. [6] Similarly, people ask, What is the difference between jumping on top of a bus? The only difference is that when you are on top of the bus, there is air pressure (aka wind) blowing in your face. If bus is moving at 60 mph, there is a 60 mph wind, which is quite strong. So, when you jump, this wind tends to push you back. If there was no air resistance, then your jumps inside and outside would be equally uneventful. [6] Then, What is the state of motion when moving in a bus? When we are moving in a bus ,we are in rest w.r.t the person in the bus and in motion w.r.t the person from outside . So state of motion depends on frame of reference. When we are moving in bus we posses the velocity of the bus . When jump from the bus that momentum makes us to move forward and pushes us forward. [6] Similarly, What happens to the kinetic energy of a bus when it crashes? The force is either a cause or result in the change of momentum mass of bus times the velocity of the bus - which goes from some high number to a small number after going splat. Thus all of the bus’s kinetic or moving energy is passed to the wall, with some being turned into heat as well. [6] Additionally, What happens to a bus when it hits a stationary object? If the bus is driving a 60km per hour, than all the passengers and driver are as well - relative to the outside. If the bus crashes it what would be considered a stationary object it would very rapidly decelerate to 0 km/h. [6] Additionally, How did the man fall off the bus? Initially he is moving in the direction of the bus as he is on the bus. As he steps on the ground his feet stop moving in the direction of the bus but his upper body continues to do so (Newtons 1st law). If his top half moves forward and the bottom half stays still he overbalances and falls in the direction of the bus. [6] References

We’ve written a lot about brains over the past three years. We send out suggested reading materials about the brain for teachers every few months, but, our readers are always asking about brainy reads for kids. We’re so happy to hear that many of our teacher readers are interested in having their students learn more about the brain! We’ve curated a list of some of our favorite free digital resources about the brain for student readers. You can use these with students, provide this list as individual reading options, or just read them yourself! Journal Articles for Kids!Many current practices in science education attempt to get kids “thinking like a scientist.” Most scientists read and contribute to academic journals, so we were pretty excited to find Frontiers for Young Minds - an open-access scientific journal for kids! It’s a really cool resource for the classroom and more specifically for students who are researching the brain. From class projects to some fun independent reading, these articles are great resources for students interested in the brain and nervous system. We highly recommend The Reading Brain, as well as articles about brain and behavior and Why We Can’t Replace Our Brains with the Internet. Although these articles are written for a younger audience, there are fun, quick reads for adults too! Videos and ActivitiesThe Kids Health website offers a fun video and complementary activities about how the brain works. The video and accompanying materials are offered in both English and Spanish and include closed captions. The video is appropriate for younger students, but can also work with older students and adults. For older students interested in the brain and nervous system, Kids Health offers a high quality article that includes embedded text-to-speech and is available in Spanish for increased accessibility options - in fact, almost all KidsHealth.org materials offer these accessibility features. National Geographic Kids offers an introductory article about Your Amazing Brain, as well as 5 Reasons Why Your Brain is Mind-Blowing. The site also offers and array of videos and games about how the brain works. We really enjoyed the video about optical illusions. Lesson Planning ResourcesWant some brainy lesson plans? If you’re interested in teaching students about the brain, Kids Health offers several lesson plans and materials for grade spans 3-5, 6-8 and 9-12. We recommend using these plans as a starting point and adapting the lessons and materials to meet the needs of all of your students. If you need help thinking through how to use these basic guides and materials to create accessible learning activities, we recommend checking out the Universal Design for Learning framework. We hope these brainy resources are a good fit for your curious students. We selected materials that were accessible to younger audiences, but still offered valuable information for teachers, so don’t hesitate to add some of these quick articles to your reading list! |
