Use a battery to turn the starter motor on a vehicle. Use petrol/diesel fuel to run an automobile. Pull the elastic on a catapult and let go to propel a stone. Fire a gun.
To know what sort of energy is being changed, we need to know what is doing the changing. If your asking what stored energy is being changed into mechanical energy, that answer is potential energy.
Mechanical energy is energy of motion, kinetic energy, and is not 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.
By burning the coal. The stored chemical eneregy is converted to heat energy. That may be used to create steam. Expanding steam pushes a piston or turbine, converting the heat energy to mechanical energy.
Stored mechanical energy can be in the form of both kinetic and potential energy. For example, a wound-up spring contains stored potential energy, while a spinning flywheel contains stored kinetic energy.
Stored energy is typically changed into kinetic energy or thermal energy when it is used.
Stored mechanical energy is the potential energy that is stored within an object due to its position or configuration in a mechanical system. This energy can be released and converted into kinetic energy when the object is put into motion. Examples include a compressed spring, a stretched rubber band, or a raised object.
motion, mechanical energy
Mechanical energy is combination of potential and kinetic energy. Chemical energy is stored in an object.
Stored mechanical energy refers to the potential energy stored within a mechanical system due to its position or configuration. This energy is ready to be converted into kinetic energy when the system is released or activated. Examples include compressed springs, stretched rubber bands, or elevated objects.
Energy stored in a moving body, (Bullet)
Yes. Chemical energy, changed to heat energy, changed to mechanical energy.
