What is the relationship between matter and energy? | Socratic
Answers to the most frequently asked science questions. If the energy could be directly converted to matter, how long would it take a person on a bicycle-type. First of all, if there were no dark matter (DM), you wouldn't ask this question, since structures — including galaxies, stars, planets, and you. In fact, emotional intimacy in a relationship is just as important to "At the beginning of a relationship everyone is high on NRE (new relationship energy). trigger that NRE again, no matter how long you've been together.
Ocean and aquatic scientists and engineers study a variety of types of matter and energy. For example, biogeochemists describe how matter is cycled and energy is transformed at large and small scales. Biogeochemists might examine cycles of elements and compounds such as water, carbon, and mercury Fig.
Some ecologists examine the variation in stages of decomposition of whale falls. Ocean engineers are developing ways to transform wind and wave energy at sea into usable electricity for people in coastal regions and beyond.
According to the framework, the crosscutting concept of energy and matter can be used to develop understanding across physical, life, and Earth science disciplines. So we get vf squared is equal to 2 times the force divided by the mass times the distance.
And then we could take the square root of both sides if we want, and we get the final velocity of this block, at this point, is going to be equal to the square root of 2 times force times distance divided by mass. And so that's how we could figure it out.
What is physics?
And there's something interesting going on here. There's something interesting in what we did just now. Do you see something that looks a little bit like work? You have this force times distance expression right here. Force times distance right here. So let's write another equation. If we know the given amount of velocity something has, if we can figure out how much work needed to be put into the system to get to that velocity.
Well we can just replace force times distance with work. Because work is equal to force times distance. So let's go straight from this equation because we don't have to re-square it. So we get vf squared is equal to 2 times force times distance. Took that definition right here. Let's multiply both sides of this equation times the mass.
So you get mass times the velocity. And we don't have to write-- I'm going to get rid of this f because we know that we started at rest and that the velocity is going to be-- let's just call it v.
Quarked! . How are matter and energy related?
So m times V squared is equal to 2 times the work. Divide both sides by 2. Or that the work is equal to mv squared over 2. Just divided both sides by 2. And of course, the unit here is joules. So this is interesting.Matter vs Energy
Now if I know the velocity of an object, I can figure out, using this formula, which hopefully wasn't too complicated to derive. I can figure out how much work was imputed into that object to get it to that velocity.
And this, by definition, is called kinetic energy. This is kinetic energy. And once again, the definition that Wikipedia gives us is the energy due to motion, or the work needed to accelerate from an object from being stationary to its current velocity. It's a very common formula. And I'll leave you with that and that is one form of energy. And I'll leave you with that idea.
Introduction to work and energy
And in the next video, I will show you another form of energy. And then, I will introduce you to the law of conservation of energy. But how can you determine if your current romantic partner is the best of the best for you? This kind of assessment comes up in a variety of contexts. Consider, for example, something that may seem entirely unrelated to relationships: The task requires wading through dozens and dozens of highly qualified candidates, each with various outstanding characteristics, to determine who warrants permanent enshrinement.

Still, no candidate is absolutely perfect — just like finding a quality relationship partner. Instinct adds nuance to hard numbers There are two general ways to make assessments: In a sport like baseball, with a plethora of statistics, a data-based approach makes sense. But for a player to be truly Hall of Fame worthy, numbers may not tell the whole story. It should be visceral, a player should feel like a Hall of Famer. But intuition is an important component of decisionsespecially social ones.
Clearly, people rely on instincts in a variety of situations such as deciding which job to take, which daycare is best, and who you should date.
Trusting your own feelings is sometimes necessary because expert information is hard to access — published research articles are often locked behind paywalls — or written in a way that defies comprehension. And of course, the very nature of science and statistics is to focus on what is most typical in a population, instead of what is best for any individual.
In fact, some experts admit to using intuition themselves.
