FAQ: How do we calculate the energy we used to do something? How do we calculate the energy used to lift an object? To calculate the energy used to lift an object, you can use the formula for gravitational potential energy: E = mgh, where E is the energy in joules, m is th...
In the majority of family homes, it’s common for children to be given the smallest rooms. They are, after all, the smallest people. But where grown-ups have the rest of the house to fill with their accrued material wealth, children’s only freedom to decide what they do and where thi...
Energy-efficient products and services can cost more than conventional ones, but the electricity savings from energy-efficient measures should eventually offset their extra cost. To calculate the time it will take to break even on energy-efficient purchases, you need to know the product's type and...
Kinetic energy is also known as the energy of motion. The opposite of kinetic energy is potential energy. The kinetic energy of an object is the energy that the object possesses because it is in motion. In order for something to have kinetic energy, you

The W-4 form helps your employer’s payroll system calculate the taxes to take out of your paychecks. The goal of taxation is to withhold, over the course of the year, a close estimate of what you’ll owe when you complete your tax return. Step 1: Enter your basic information. Then ...
To calculate the MARTS data set each month, the Census Bureau pulls a random sample set of roughly 4,800 retail companies (and company business units) from the MRTS pool and asks them to respond to a questionnaire. The results are weighted by category and seasonally adjusted to account for ...
There are several ways to calculate CDD. The more detailed a record of temperature data, the more accurately the CDD can be calculated. Here are examples of two ways that are often used. Subtract 65 from the average of a day's high and low temperatures. For example, if the day's avera...
