What is the mechanical energy of an object?
Mechanical energy is heat light and kinetic energy but instead of saying something has heat light and kinetic energy we just say mechanical! :)
A moving object must have potential energy?
An object that has kinetic energy must have momentum, velocity, and speed. Momentum is mass times velocity. Kinetic energy is mass times velocity squared. Speed is distance divided by time. Kinetic energy is the energy of the object's motion. An object that has kinetic energy must have momentum because is the force or speed of movement. For example the ball gained momentum as it rolled down the hill. An object that has kinetic energy must have momentum, velocity, and speed because if an object is in motion (has kinetic energy) it must be either gaining, losing, or at a constant momentum, it must have a velocity (basically speed) and speed because when an object is in motion, it MUST have a certain velocity or speed.
What is energy that is associated with motion or position of an object?
It is internal energy that drives atoms or molecules in a random manner
Can energy be used up or can energy be lost?
Energy isn't "used up" but instead is converted into different forms like heat (thermal) and motion (kinetic) but when talking about an object we say the object has lost or gained energy.
What kind of energy does potential energy change into?
If an object falls down, potential energy will be converted into kinetic energy (energy of movement). However, if an object drifts down slowly - say, a feather falling in air, or an object that falls down in water - the energy will be immediately converted to heat energy.

Mechanical energy is heat light and kinetic energy but instead of saying something has heat light and kinetic energy we just say mechanical! :)
Which has more kinetic energy- A small object or a large object moving at the speed of 25 mph?
You don't say what speed the small object has. If both have the same speed then the heavier one will have more kinetic energy.

Why is electricity a form of kinetic energy?
I believe electrical energy is considered potential energy and not kinetic. Kinetic energy is when an object is moving, electrical energy is a stored energy that can be converted to kinetic energy.
How is sound energy is formed?
sound energy is formed by a vibrating body. We can say that sound is produced only when a body is vibrating.
What happens to the kinetic energy when an object moves faster?
it gets greater because the greater the mass the greater kinetic energy
Can energy be used up or can energy be lost?

Is the following sentence true or false kinetic energy is related to an objects height?
Only in a particular way. Kinetic energy is given by the formula 1/2 X mass of object X Velocity of object X Velocity of object. So if, say, a car of mass 1000 kg was travelling along a level road with a velocity of 10 metres per second, its kinetic energy would be 1/2 x 1000 x 10 x 10 or 50000 Joules If the car was travelling along a different road, higher up a mountain, say, doing the same speed, then the kinetic energy would be the same. So in this case the kinetic energy would be unaffected by height. HOWEVER... If the car fell from a cliff, then the height of the cliff wouldmatter. A short drop would mean that when it hit the ground the car's velocity would be small, and so its kinetic enery would be small. From a high cliff it would fall more distance, and so the car would have more time to acellerate to a greater speed (as gravity pulled it down) so that when it hit the ground it would be travelling quickly and hence its kinetic energy would be high. Height affects Potential Energy - the greater the height the greater the energy. If the car is high up, the large amount of potential energy is converted into a large amount of kinetic energy as the car falls. On impact the kinetic energy turns into sound (the crash) and heat.
As you say the black holes rotate in spirlish motion where does the energy for spirlish motion come from.?
As the gravitational potential is converted into kinetic energy by the object falling down the energy gradient.
