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.
Not necessarily. An object can have kinetic energy without having potential energy. For example, a moving car has kinetic energy but may not have any stored potential energy depending on its position.
Yes, in raising an object, there must be an increase in potential energy that the object possesses.
If the speed of a moving object is doubled, the object's kinetic energy must also double, as kinetic energy is directly proportional to the square of the object's speed.
Mass.
To calculate the potential energy of an object, you need to know the object's mass, the acceleration due to gravity, and the height at which the object is located. The formula for potential energy is PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.

work=change in kinetic energy, doing work on an object by moving it up increases that object's potential energy because it has the POTENTIAL to fall due to gravity. kinetic energy is lost in the movement of the object. However, throughout an entire closed system, the total energy in joules (or kinetic enery plus potential energy) does remain constant. this is useful because the initial energy and the final energy most be equal, and if thats true, then initial kinetic energy plus initial potential energy must equal final kinetic energy plus final potential energy. does that help?

The relationship between work and negative potential energy is that work is required to move an object from a higher potential energy state to a lower potential energy state. Negative potential energy indicates that the object is in a lower energy state compared to a reference point, and work must be done to move the object further away from this reference point.
Mechanical Energy= Potential energy+ Kinetic energy, so for the mechanical energy to be equal to be potential energy, the kinetic energy must be 0.

Yes, potential energy associated with a charged object is due to its position in an electric field. When the charged object is positioned in an electric field, work must be done to move the charged object to a different position, resulting in potential energy stored in the system.
The assumption made is that the height of the object is constant as it is lowered into the deep hole. This means that the potential energy of the object decreases linearly with respect to the depth of the hole.
