The idea here is to write the equation for gravitational potential energy:GPE = mgh
(mass x gravity x height), then replace the numbers you know, and solve the resulting equation. You can assume Earth's gravity to be about 9.8 newtons/kilogram.
The SI unit for work and energy is the joule.
Potential energy is measure in Joules (J). A Joule is a Newton*meter (N*m)
1 calorie is equal to 4.186 joules. sausage is 50 calories or 209.3 joules of energy. banana is 105 calories or 439.53 joules of energy. Therefore a peeled banana contains much more joules of energy than tasty looking sausages. ;)
Well, 40 percent of 250 I guess! Which, if you are not good at arithmetic is 100 Joules.
Momentum does not have the same units as the others. Kinetic energy is measured in joules, potential energy in joules, work in joules, but momentum is measured in kilogram meters per second (kg m/s).
A kilogram of wood contains potential energy in the form of chemical energy. The exact number of joules can vary depending on the type and dryness of the wood, but on average, 1 kilogram of wood contains about 15,000-20,000 joules of energy when burned.
the units for gravitational potential energy is joules (j)
The gravitational potential energy gained by lifting a 1 Newton book 4 meters is 4 Joules. This is calculated by multiplying the force (1 Newton) by the distance (4 meters) to get the energy in Joules.

The SI unit for work and energy is the joule.
Potential energy is measure in Joules (J). A Joule is a Newton*meter (N*m)
The mechanical energy of the satellite is the sum of its kinetic energy and potential energy. In this case, the mechanical energy would be 182.2 billion Joules (kinetic energy) plus 1.6 billion Joules (potential energy), totaling 183.8 billion Joules.
Energy is measured in joules.
The potential energy gained by a 1kg book elevated 4m can be calculated using the formula: potential energy = mass * gravity * height. Plugging in the values, we get potential energy = 1kg * 9.8 m/s^2 * 4m = 39.2 Joules.
1 calorie is equal to 4.186 joules. sausage is 50 calories or 209.3 joules of energy. banana is 105 calories or 439.53 joules of energy. Therefore a peeled banana contains much more joules of energy than tasty looking sausages. ;)
The total energy in a system is the sum of its potential energy (PE) and kinetic energy (KE). In this case, with a total energy of 30 joules and potential energy of 20 joules, we can use the formula: Total Energy = Potential Energy + Kinetic Energy. So, KE = Total Energy - PE = 30 J - 20 J = 10 joules.
The metric unit of potential energy is the joule (J).
