Positional energy is the energy stored within an object due to the objects position arrangement or state positional in energy is one of the two main forms energy along with kinetic energy
Answer:
Second Law
Explanation:
Newton's second law states that the acceleration caused in a body is directly proportional to the force applied and inversely proportion to the mass of the body.
This is given by :

In this case the suggestion given to reduce the aircraft's cargo load is the right move as reducing the load on the aircraft will decrease the mass of the whole aircraft. This in turn will help the aircraft to accelerate more as acceleration inversely varies with mass. Thus the aircraft will be able to reach its flying speed even on a short run way.
Hence, Newton's second law is applied.
Burning charcoal is a chemical reaction called combustion
Reactants would be the missing word in the sentence because they make up the products in a chemical reaction
