Storage form of energy:
- Potential energy
- Nuclear energy
- electrical energy
- thermal energy
- magnetic energy
Potential energy:
All stationary objects are having potential energy stored in it. This energy can be transferred in form of kinetic energy when it comes in the motion from rest. Example, An object placed at height h having potential energy in it. When it comes in motion from the rest the potential energy is converted into kinetic energy.
Nuclear energy:
Nuclear energy is energy that is stored in nucleus of any element. Example, fusion reaction on sun gives earth solar energy.
Electric energy:
Electrical energy is due to movement of the electrical charges. Example, In elctrical batteries electrical energy is stored.
Thermal energy:
Thermal energy is the internal energy of a substance that is transferred to other substance in the form of heat. Example, on heating water is a beaker stem energy is developed.
Magnetic energy:
Magnetic energy is the potential energy stored in the magnetic field. Example, using magnetic energy electric field is produced according to Faraday's law.
Answer:
30mph
Explanation:
7.5 miles / .25 hours = 30 mph
The right answer for the question that is being asked and shown above is that: "The object's kinetic energy remains the same." If the net work done on an object is zero, you determine about the object's kinetic energy is that The object's kinetic energy remains the same.
Newton's first and second laws of motion both do, but I think the one you're looking for is: <em>The First Law of Motion</em>. That description is a little more direct.
It says that if an object is not acted on by a net external force, then it continues in "constant, uniform motion".
