Explanation:
Activation energy and reaction rate
The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. ... The released energy helps other fuel molecules get over the energy barrier as well, leading to a chain reaction.

Explanation:
What math class are you in I think I can help
Explanation:
<em>Law of conservation of energy states that the energy of a system is always constant. </em>
In other words, we can say that energy can neither be created nor destroyed.
Mechanical energy (E) is the sum of the potential energy (U) and the kinetic energy (K) of the freely falling body. Therefore, <em><u>E=K+U=constant.</u></em>
