Answer:
The three laws of motion were first compiled by Isaac Newton in his Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687. Newton used them to explain and investigate the motion of many physical objects and systems
Answer: 
Explanation:
The heat (thermal energy) absorbed by the iron skillet can be found using the following equation:
(1)
Where:
is the heat (absorbed)
is the mass of the element (iron in this case)
is the specific heat capacity of the material. In the case of iron is 
is the variation in temperature
Knowing this, lets rewrite (1) with these values:
(2)
Finally:
Answer:
Natural gas is non renewable energy.
Explanation:
Because they were formed from the buried reamains of plants and animals that live a million years ago. It is formed from fossil fuels.
Answer:
Explanation:
An object falling loses gravitational potential energy and gains kinetic energy. The gravity potential is the gravitational potential energy per unit mass. This energy comes from the gravitational potential energy released when the water falls. ... At 0, all the energy is in gravitational potential energy.
