This table is based upon a dog's Resting Energy Requirements or RER. The RER is the basic amount of energy that a dog would use in a day while remaining at rest. The formula to calculate RER for animals between 2 and 45 kg (5 - 99 pounds) is: RER in kcal/day = 30(body weight in kilograms) + 70. Any activity or variable other than rest will require an increase in energy (RER) and an increase in calories to meet the energy needs. Realize that these numbers are not a reflection of maintenance calories but of resting energy levels.
Kinetic energy is the energy of motion, and is given by the equation E = (1/2) m v. If m is in kg, and v in m/s, then E is in joules. A one gram rock (m = 0.001 kg) moving at 2.4 km/sec (2400 m/s), has kinetic energy is 2645 joules = 0.6 Calories, approximately equal to the chemical energy stored in a gram of TNT.o if you cut back by 500 Calories per day, you will consume about 70 grams of your own fat per day, 500 grams per week, equal to a little more than a pound per week. Alternatively, you can lose that pound per week by working out at 1/7 horsepower for one hour every day, seven days per week.
