100 kW is not an energy, it is a power. It is the same as 100 kJ/sec (100,000 joules/second. The 100 kW - or 100 kJ/second - can be converted to 100 kW of mechanical power - or less, depending on the type of energy, and how much is wasted.
It is an energy that is done through machines.
It is an energy that is done through machines.
energy acquird by the objects upon which work is done is known as mechanical energy Mechanical energy is found by adding kinetic energy and potential energy.
Work is related to mechanical energy because when work is done on an object, it can change the object's mechanical energy. Mechanical energy is the sum of an object's kinetic energy (energy of motion) and potential energy (stored energy). When work is done on an object, it can increase or decrease the object's kinetic or potential energy, thus affecting its overall mechanical energy.
When mechanical work is done on a system, there is an increase in the system's internal energy. This increase in internal energy is due to the transfer of energy from the mechanical work applied to the system.
When mechanical energy decreases and temperature increases, it is likely due to the conversion of mechanical energy into thermal energy. This happens through processes like friction or resistance, where the mechanical energy is transformed into heat, causing the increase in temperature.
When you lift a stool, you are mainly using mechanical energy. This involves the work done by your muscles to raise the stool against the force of gravity.
The energy used to turn a bolt with a screwdriver is mechanical energy. This mechanical energy is converted from the work done to rotate the bolt, transferring energy from the screwdriver to the bolt.
When mechanical work is done, the internal energy of a system can change. If work is done on the system, the internal energy increases. Conversely, if work is done by the system, the internal energy decreases. This change in internal energy is governed by the first law of thermodynamics.
The mechanical wave's energy can be directly measured using instruments like a power meter or a calorimeter. These devices can quantify the wave's energy by measuring the amount of work done by the wave as it travels through a medium.
No mechanical energy is needed to hold up an object. Mechanical work (transfer of energy) is done when applying a force over a certain distance. Don't confuse force and energy (or force and work).
Mechanical energy can be converted into other forms of energy such as thermal, electrical, or sound energy, depending on the system in which the conversion takes place. This conversion occurs due to the work done by the mechanical energy on the objects or materials involved in the process.
