Mechanical energy is the energy of moving objects, such as the energy that you use when you physically move something with your hand. Obviously, movement is a form of change, it constitutes a change of location or position. Often there is a change of momentum involved as well (as for example when you throw something).
Energy either transfers to the object or leaves the object.
doing work changes the energy because energy is begining transferred to the object and the power will be equal to the amount of energy transferred.
Kinetic energy is the energy of motion; a thrown object has kinetic energy.
Kinetic energy depends on mass, and speed. Since you can't easily change an object's mass, you would basically change its speed.

The object has energy.
When an object absorbs light energy the object can get warmer.
Energy either transfers to the object or leaves the object.
potential energy
the Work-Energy Theorem states the work done is equal to the change in kinetic energy.
The kinetic energy of the object changes into thermal energy.
You need energy for metabolism and energy is the ability to cause a change
The object has energy.
The object has energy.
