Thermal energy - the internal kinetic energy in a substance caused by vibration of atoms and molecules. Thermal energy is also known as heat.
Radiant energy - is the electromagnetic energy that travels in waves. Radiant energy is kinetic energy that includes light, x-rays, microwaves, and radio waves.
Elastic energy - potential energy produced from stored or released elastic materials. This is stored mechanical energy energy resulting from being stretched or compressed.
Mechanical energy - the energy an object possesses due to movement. Mechanical energy is kinetic energy because it is the movement from one position to another.
Gravitational energy - the potential energy an object has because of position. This is produced from gravitational force acting upon an object.
Chemical energy - the potential energy stored in the bonds of molecules and compounds.
Nuclear energy - potential energy stored in the core (nucleus) of an atom.
Electrical energy - the kinetic energy produced from the movement of an electric charge.
Very efficient because it uses less then half to do the action then the vacuum actually stores.

Answer: 294 N
Explanation:
Since the Normal Force 
is equal to the weight 
of the dog, we have:
Where:
is the mass of the dog
is the acceleration due to gravity on the Earth's surface
Solving:
Answer:
4.3 g/ cm^3
Explanation:
Mass / Volume = density . so 2150/500= 4.3 g/cm^3
