The term ‘kinetic’ has come under fire recently with some consumers complaining of dizziness, nausea, and other symptoms from consuming a product with a very high calorie count.
The problem is, it can be hard to understand exactly what a kinetic energy unit is.
While there are several ways to get a feel for what a kilojoule is, you can’t actually measure the energy produced from that energy source.
But with this new research from a University of California, Berkeley team, you will be able to accurately gauge your energy expenditure in an accurate manner.
The Berkeley team has been working on their Kinetic Energy Units (KEVs) for the last few years, and in a study published in the journal Energy, they were able to create a new type of unit that is both accurate and convenient.
“We found that the Kinetic Unit used by our lab and others has the greatest predictive ability,” said study lead author Eric Hahn, a PhD student in energy science.
“The Kinetic unit was actually the first energy unit to be tested in this fashion.”
The researchers were able predict the energy consumed by a single person using a Kinetic Units scale, which was designed to be used with a standard measuring device and an energy-related device.
The Kinetic units are designed to measure the kinetic energy of a unit, such as a car battery.
In other words, they are designed for measuring a quantity of energy, not the actual energy produced.
“This is important because we know that the energy we expend in everyday life is much more than what we consume,” said Hahn.
“It is also important because this measure is a good indicator of how much energy we are consuming, and it helps us decide whether to invest in a product that can help us meet our energy needs.”
The Kinetics unit measures the kinetic energies of a single human, which is a very important factor to understand when purchasing a product like a car, because these energy-saving products are designed specifically to meet the needs of a small group of people.
“The Kinetically Unit is a useful tool for determining the energy consumption of individuals.
In particular, it is useful for predicting energy use in a population that is small and heterogeneous,” said Andrew Pachter, a professor of mechanical engineering at the University of Texas at Austin.
“Kinetic Units are also useful in measuring energy consumption in a particular population, such a a school of fish.”
To determine how energy was consumed by students in the laboratory, the Kinetics units were used to measure each student’s total daily energy expenditure.
The study found that students who had been consuming energy-efficient products were able, on average, to consume between 1.4 and 2.1 kilojoustes (kJ) of energy per day.
In contrast, students who were consuming less energy-intensive products were more likely to consume less energy per calorie than students who ate more energy-rich products.
“In general, we can estimate the energy used by individuals by measuring their daily energy intake using Kinetic Systems,” said Pachtner.
“However, when students are in a specific environment, they can’t measure their daily metabolic rate or their energy expenditure.”
“For example, in the classroom, students might consume 1.5 kilojos per day and be exposed to more than two different types of energy,” said Chris Hahn of Berkeley.
“As a result, their Kinetics Units might only provide an estimate of their daily consumption, but they are not able to distinguish between different types or energy consumption patterns.”
The research also showed that the average Kinetic System predicted energy use to be more accurately related to the daily energy consumption than was previously believed.
The researchers believe that this may be due to their design.
For example, the devices they used had a design that allowed them to calculate energy use from the kinetic force created when they were activated, which may have prevented students from using more energy than they were being exposed to.
In the future, the researchers plan to use this new energy-saving technology to measure energy usage in the field of nanotechnology, which will help them develop more efficient energy-absorbing materials.
The research is published in Applied Physics Letters.
