Heat always flows from hot to cold. Cold is the absence of heat.
Energy can be considered an abstract noun because it represents a concept or idea rather than a tangible object that can be seen or touched.
An object that you can perceive is called a tangible object. Tangible objects can be seen, touched, smelled, heard, or tasted.
kinetic- work done by an external force from bringing the object to a rest then to movementpotential- unknown sourcekinetic energy is the energy or force of any motion, and everything, whether it is object, particles, molecules or person has motion. Everything that is moving, either by their own force or by any other force is considered to have kinetic energy.
When you lift an object, you are transferring energy in the form of work done against gravity. This added energy gives the object potential energy, which is stored energy due to its position relative to the earth's surface.
No, the energy that flows from a hot object to a cold object is called heat energy. Kinetic energy is the energy of motion of an object.

Objects in motion have kinetic energy and objects at rest have potential energy. Whether or not the object in motion has more energy than the same object at rest or vice versa depends on specific circumstances. It depends on the speed of the object in motion.
Generally yes, but it really depends on the specific situation. -- If the work is done to lift the object, then the object's potential energy is increased. -- If the work is done to accelerate the object, then the object's kinetic energy is increased. -- If the work is done to move the object against friction, then the energy supplied is dissipated, and the object's energy may or may not change, depending on whether or not it is somewhat heated by the dissipation.
Not always. It depends on the object.
Energy is a conserved quantity. That means that, if no energy enters or leaves an object, the total energy of this object will remain the same. There are several ways for energy to enter or leave; I am not sure whether all of these qualify as "work".

That sounds like a description of potential energy. However, the energy is not BECAUSE the object is at rest; rather, it's energy related to an object's position, with respect to other objects (specifically, if there is some force involved). For example, an object at a height of 100 meters will have a certain amount of gravitational potential energy - regardless of whether it is moving or not.
All substances above absolute zero emit radiant energy. Whether the object emits more than it absorbs depends on its temperature compared to the temperature of its surroundings. An object warmer than its surroundings will usually be a net emitter.
OB-ject - noun- He brought an ugly object to school. ob-JECT - verb - I object your honour!
The energy of a moving object is called the Vector energy. It is also called Kinetic energy but there is a distinction between Potential energy a real energy and vector energy a vector. it is not clear in physics whether Kinetic energy is a vector or real energy. For example 1/2 mv^2 is called kinetic energy but it is not vector energy.
Heat has the natural tendency to flow from a warmer to a colder object. If your hand is warmer than the "cold object", then heat will flow from your hand to that object.
