It doesn't quite make sense for that to happen. Obviously it doesn't make sense from the point of view of energy conservation. Also, mechanical energy consists of kinetic energy - so all objects would suddenly have to stop moving. Mechanical energy also consists of potential energy (including gravitational potential energy), so all objects would suddenly have to be at the lowest possible gravitational potential - presumably, all objects in the Universe would have to come together into a black hole or something like that.
If there were no mechanical energy, there would be no movement and so no life exists.
secret
Anything could happen when a rabbit disappears.
One method which this could happen is you have mechanical energy, lets say you riding a bike, and attach a turbine to it which converts your mechanical energy into electrical energy. You then plug a light bulb into that, and the electric energy is converted into light.
That is normal for example when energy is transformed from mechanical directly into electrical i a generator, or electrical to mechanical in a motor.
you will not do or move
Electrical into magnetic, and then magnetic into mechanical.
Then the motor will act as generator by principle
I don't know
It will not get enough energy. It will malfunction with time
well what had happen was..... it makes generate heat, electrical, mechanical, and sound energies
The Floods that happen suddenly are called Flash Floods.
