When only mechanical energy acts on an object what is conserved?
When only mechanical energy acts on an object, the total mechanical energy of the system is conserved. This means that the sum of the object's kinetic and potential energies remains constant, assuming no external forces or sources of energy are involved.
When only air resistance acts on an object mechanical energy is conserved?
No, when only air resistance acts on an object, mechanical energy is not conserved. Air resistance dissipates the mechanical energy of the object by converting it into other forms of energy, such as heat and sound, causing the object to slow down and lose kinetic energy over time.
How is mechanical energy stored?
Mechanical energy is stored in objects through their positions or motion. Potential energy is stored in an object's position or shape, while kinetic energy is stored in an object's motion. When an external force acts on the object, this stored mechanical energy can be released and converted into other forms of energy.
Are there any situations in which a frictional force can increase the mechanical energy of a system?
No, friction always acts in the direction opposite to the motion of an object, which dissipates mechanical energy in the form of heat. Therefore, friction cannot increase the mechanical energy of a system.
Can an object be in mechanical equilibrium if only a single for acts on it?
No.
What is the relationship between mechanical energy and work?
Work is the quantity of energy being transfered (i.e. potential to kinetic). It is due to work that energy is transfered between potential and kinetic and vice versa. This is an attribute of the first law of thermodynamics. Energy is also the ability to do work
Can a object be in mechanical equilibrium when only a single force acts on it?

What is mechanical work done?
Mechanical work is the transfer of energy that occurs when a force acts on an object and causes it to move. It is calculated by multiplying the force applied to the object by the distance over which the force is applied in the direction of the force. Work is measured in joules (J).
Work is transfer of?
Work is the transfer of energy between a system and its surroundings, resulting in the displacement of an object from one location to another. It is a scalar quantity that measures the amount of energy transferred when a force acts on an object over a distance.
Are mechanical energy and work the same thing?
A1 Mechanical energy is energy produce from raw materials which are burnt, such as oil, work is the use of energy ehich may be mechanical, or physical, which means the use of foods to produce energy which is then used for work, so no, they are not the same thing A2 Energy and work have the same units, ie Joules in the SI system, and the dimensions are Force x Distance, or Newtons x Meters. I always think of work as the use of energy. Thus for example you release energy from a fuel such as gasoline by burning it, and use this energy to do work, ie propelling a car.
Is the transfer of energy that occurs when a force makes an object move?
The transfer of energy that occurs when a force makes an object move is called work. Work is a quantity of energy given in the unit of Joules. The mathematical description of work is the product of the force and the distance for which it was applied.
What is work done by a force in a mechanical system called?
The work done by a force in a mechanical system is called mechanical work. It is the transfer of energy when a force acts on an object to move it over a distance. Work is calculated as the product of the force applied and the distance moved in the direction of the force.
