nm,.kjhgfvdx Ronnie wants to investigate the effect of height on the number of times a ball bounces back. He drops the ball from three different heights (1 m, 1.5 m, and 2 m). If the ball bounces back 12 times from the 1.5 m height, which of the following is a possibility for how many times the ball bounces from a 1 m height?

8 times because the ball will have more mechanical energy
15 times because the ball will have less mechanical energy
8 times because the ball will have less mechanical energy
15 times because the ball will have more mechanical energy

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

i don,t know so just answer mine
