The distance of the book from the floor can be calculated using the formula for gravitational potential energy: PE = mgh, where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity (approximately 9.81 m/s^2), and h is the height. Rearranging the formula to solve for h, we get h = PE / (m * g). Plugging in the values, h = 196 J / (5 kg * 9.81 m/s^2) ≈ 4 meters. Therefore, the book is approximately 4 meters from the floor.
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 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.
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.

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)

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.
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.
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 metric unit of potential energy is the joule (J).
