How many joules of potential energy does the pendulum have when it has 100 J of kinetic energy?
When the pendulum has 100 J of kinetic energy, it has 100 J of potential energy as well because the total mechanical energy (potential energy + kinetic energy) remains constant in an isolated system like a pendulum. Therefore, the total energy would be 200 J.
A satellite falling to the earth has kentic energy of 182.2 billon Joules and a potential energy of 1.6 billion JoulesWhat is its mechanical energy?
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.
What is kinitic and potintial energy?
Kinetic energy is the energy possessed by a moving object, calculated as ½mv2. If m is the mass in kg and v the speed in metres/sec the answer will be in joules. Potential energy is sitting there waiting to be turned into kinetic energy. Examples are a mass on a shelf, that will gain kinetic energy if it is dropped off, or energy in a pendulum at the top of its swing when it is stationary. With a pendulum the energy is continually exchanged between potential and kinetic and the total energy (ignoring friction) stays the same (with a real pendulum the total energy runs down because of air resistance).
If we know the total in a system is 30 joules and we know the poteial energy is 20jolueswhat is the KE?
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.
What unit use for work potential and kinetic?
Work uses the same unit as energy. Ideally, you would use the same units for work, potential energy, kinetic energy, or any other type of energy. In the SI, that is the joule.

What is a comparison of kinetic and potential energy?
They are both measured in Joules

What does not have the same units as the others Kinetic Energy Momentum Potential Energy or Work?
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).
Suppose a falling object loses 7J of potential energy. How much kinetic energy will it gain?
From what I understand: PE - Potential Energy (mgh) KE - Kinetic Energy (1/2 mv2) If one dismisses the friction with air (conservation of energy), a loss of 7 joules for potential energy means a gain of 7 Joules in kinetic energy.

Similarities between Kinetic energy potential energy electric energy and gravitational energy?
they are both measured in joules
What is the similarities between kinetic energy and potential energy?
kinetic energy depends on speed an potential energy depends on height and mass
What can be measured in joules?
Various forms of energy can be measured in joules, such as kinetic energy, potential energy, heat energy, and electrical energy. Joules are a unit of measurement for energy and can be used to quantify the amount of energy present in a system or the amount of work done.
When an object falls which energy changes to?
As the object falls, it PEG or potential gravitational energy becomes kinetic energy. Before falling, it has for example 10 joules of PEG and 0 joules of Kinetic energy. As it falls, the PEG decreases and the kinetic energy increases, until it hits the ground, when all the energy is dispersed as sound, heat, etc.
