An 8.8 kg object is falling from a height of 1.9 m at 1.57 m/s. What is the total energy of the object? A satellite of mass m is in a circular earth orbit of radius r. (a) Give an algebraic expression for the satellite's mechanical energy in terms of the mass of th...
The energy possessed by a body due to its state of rest or state of motion is called mechanical energy.
(a) Mechanical energy = KE + PE. (b) It is the general name of electic and magnetic energies.
What device transforms electrical energy into mechanical energy? What changes mechanical energy to electrical energy? What kind of energy is stored energy? What are the two main types of energy? What dictates the energy of a mechanical wave?

Energy is best defined as “the capacity for doing work”. Electricity is but one of many forms of energy. Other familiar forms of or descriptions of energy are thermal or heat, light, mechanical, and so on. Energy is also described as kinetic, that energy associated with a moving body,...
The mechanical energy of an object is the energy that it possesses due to its motion (speed). An object may possess kinetic energy, energy due to its motion, and potential energy, energy due to its position.Answer and Explanation:
When the oscillator is at its equilibrium position all of its energy is converted back to kinetic energy. So try and find the maximum potential eneregy of the oscillator. It might be helpfull to totally forget that you are dealing with a swing and just concentrate on the maths. Anyway, ...
