For example, a moderately active, 5-foot 5-inch, 35-year-old female that weighs 140 pounds would use the following calculations to determine her macro needs for a keto-based diet: Based on the TDEE calculator using the Mifflin St Jeor BMR formula, the total daily energy expenditure would...
Step 2 Calculate the energy the bullet will deliver to the target on impact using the formula KE=wbv2450,437 In words, the bullet energy KE (in foot-pounds) is equal to the bullet weight (in grains) wbtimes the square of the bullet velocity v (in feet per minute) divided by 450,437...
The one who has 195 pounds of lean muscle mass may have a total daily energy expenditure much closer to 3000 calories or even higher. When trying to assess how many calories each of these individuals should be taking in for weight loss purposes, as you can see, this will make a big dif...
Heat is one of the seemingly countless forms of the quantity known as energy in physics. Energy has units of force times distance, or newton-meters, but this is usually called the joule (J). In some applications, the calorie, equal to 4.18 J, is the standard unit; in still others, th...
P=F×v Watt did all of his measurements using English units, and he invented the horsepower, which he defined as the power necessary to raise a load of 33,000 pounds one foot every minute. When the metric system was adopted by the international scientific community, a watt, by virtue of...
It’s worth noting that what works best for your friend may or probably will not work for you. So if you want to get the most of this whole thing, you need to start on the right foot. We recommend that you consider working with an experienced coach when starting out with calculating ...
An 890-Newton person, wearing snowshoes, is standing on one foot on the snow posing for a picture. If the area of the bottom of the snowshoe is .1432 m^2, how much pressure is the person exerting on t A 7.25 kg bowling ball moving a...
Wide tyres and huge wheels cause a greater spinning mass, which means heavier wheels need more energy to accelerate. Wide tyres also have increased rolling resistance, reducing fuel efficiency, therefore go back to the manufacturers' basic estimates. ...
Weight in pounds divided by the square of height in inches, then multiply the result by 703. Mathematically : weight (lb) / [height (in)]2 x 703 Remember to convert ounces and fractions to decimals before plugging in the values. It’s a straightforward way to calculate BMI by considering...
Note that the spring constant has units of force/distance. In the MKS system, the spring constant units are newtons/meter. In the CGS system, they are dynes/centimeter. In the imperial system, they are pounds of force (lbf) /foot. ...
