The calorific value of diesel is around 42.7 Mega Joules per kilogram.
1 Kilo Joule = 2.777778e-007 Kwh/kg
One foot-pound of force equates to about 1.355818 joules.
42 inches = 1.0668 meterPE = M g H = (1,200) (9.8) (1.0668) = 12,545.568 joules(rounded) relative to the bottom of the hill
It depends on the variety of the wood, whether is is seasoned and dry. From 170 kg per cubic metre for Balsa to 1370 kg per cubic metre for Lignum Vitae
Joule/kilogram-kelvin The SI unit is joules / kelvin. This is valid for an object of any size, but if you want the typical specific heat for a certain type of material, you have to standardize it, resulting in either joules / (kelvin x kilogram) or joules / (kelvin x mole).
The potential energy of an object is given by the equation: PE = mgh, where m is the mass of the object (20 kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height (100 meters). Plugging in the values, the potential energy would be: PE = 20 kg * 9.81 m/s^2 * 100 meters = 19620 Joules.
You're a little high, but not nearly as much I thoughtyou were when I saw that humongous number ! 1 KG-Calorie (nutrition) = 4,190 Joules so 10,000,000 Joules = (10,000,000 / 4,190) = about 2,385 calories. This is a lot for an office worker, but not that far out for a person who is large or active; so I guess the answer is "True".
The quantities involved in kinetic energy are mass and velocity. Kinetic energy is calculated as 1/2 the mass of an object multiplied by its velocity squared. The unit of measurement for kinetic energy is joules.

To convert from kilojoules to joules you have divide by 1000. meaning 1 kilo joule is equal to 1000 joules.
