If a black hole were to explode and release all of its gravitational energy, it would result in a powerful and destructive event known as a gamma-ray burst. This burst of energy would be extremely intense and could have significant impacts on surrounding objects in space.
That could happen in an electric or hybrid car, when the car is coasting down a hill, converting gravitational potential energy to the car's kinetic energy, and a touch of the brakes puts some of that kinetic energy into the batteries. But it's a stretch.
When the height of a body is doubled, its potential energy also doubles. This is because potential energy is directly proportional to the height of an object in a gravitational field.
The energy changes from kinetic to potential when an object's motion is converted into gravitational potential energy due to its change in height or position in a gravitational field. This can happen, for example, when an object is lifted against gravity or when an object reaches the peak of its motion in a pendulum swing.
As the object falls towards the ground, its gravitational potential energy decreases and is converted to kinetic energy. This means that the kinetic energy of the object increases as it gets closer to the ground.
This can happen in many sports. One common example is anything that involves a ball - of the type that can bounce when they fall. In such a ball, when it falls down, gravitational potential energy is converted into kinetic energy; later, when it touches the ground, the kinetic energy is converted into elastic energy. When the ball bounces back, part of this elastic energy (typically, most of it) is converted back into kinetic energy.
If the sun exploded it would not give us oxygen; it would simply vaporize Earth.
you would die!

We would all die
I posted the information in the related links below.
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.
It wouldn't and couldn't
Everyone would be dead
