What is 8th grade: Definition and 12 Discussions

A science teacher ask if I could help one of her students build a "Time Dilation Clock" so, at launch the Ships chronometer and the local time are in sync. with a 3g continuous thrust, at some point the time, the time at the launch site will be going twice as fast as the ships chronometer. so...

8th-grade science student. I want to major in 9th-grade chemistry. I currently live in Pakistan. Perpetually interested and always ready for books, cats, knowledge, and cats

Hey I'm new to this forum and I'm 14 and I want to be a future Physicist (Probably Particle Physicist ) and I was wondering what books are good for starting out , just to let you know what kind of content I'm looking for I already know about General relativity , special relatativity , and the...

Hi guys, I need to create a science project, but first I need an idea. I have already come up with an idea, which was measuring stress level under timed and untimed tests, but my teacher said that it was too simple. Do you have any suggestions on any 8th Grade science projects I could do, that...

I know the question is simple... but I don't get it. A metal ball is thrown from a tall building V0= 0. When will it reach V=25 m/s? This is my first question, I seem to like physics yet I don't understand anything... accept electricity, but the rest, I don't. I hope I don't annoy anoyone but...

I am a high school student interested in physics and cosmology, but only have a math education that goes up to 8th grade (linear equations, just real simple stuff) I think I'm pretty goodarn at self teaching and want to get some books so I can work my way up to understandino physics.

I am writing a paper on the collision of two galaxies. I would like advice on using the right method to complete this project. I have found some sites about the collision of the galaxies: http://www.sciencedaily.com/releases/2014/08/140826141130.htm http://arxiv.org/pdf/1406.4859.pdf...

I am an eighth grader who is interested in hopefully pursuing a career in physics. I currently have a 100 in Algebra 1 but I want to learn more. I always read about the famous scientists such as Newton and Hawking. I feel as if I am capable of learning more then what we are learning in school...

I am in 8th Grade, and I am taking an Algebra A class. This class is basically an introduction to algebra, and next year I will take algebra 1 for math. If I wanted a career in physics, am I behind? Should I push myself to jump up a class next year? Is it necassary to take calculus before...

I want to start getting ahead more in the Algebra field. Problem is, my school is not open to students advancing ahead of where they are supposed to be (knowledge is power). So, what I want to know is some good sites where I can learn Algebra in sort of a lesson pattern, but not having to enroll...

Two stars move towards each other due to the forge of gravitation. Star 1 has twice the mass of star 2. Which if either exerts a greater gravitational force? Why?

Can anyone help me: Lifting a sail up a mast. Sail is 825 kg, the distance is 5 meters. What's the force required (in Newtons)? Thanks to anyone helping - L. I calculated this a 8085 Newtons, using gravity at 9.8 m/sec2. I need help understanding the relationship between acceleration...
