Question

which statement best describes elastic potential energy? * 2 points
energy of motion
when objects have the potential to change their position due to the force of gravity.
when the energy is stored within the matter itself (energy stored in a battery).
when something is stretched or compressed within the object (for example, stretching a string of a compound bow).

which statement best describes chemical potential energy? * 2 points
energy of motion
when objects have the potential to change their position due to the force of gravity.
when the energy is stored within the matter itself (energy stored in a battery).
energy stored in the bonds between atoms and molecules, which is released during chemical reactions (e.g., fuel, food, batteries).

Explanation:

For elastic potential energy: It is the energy stored in elastic objects when they are stretched or compressed. The option referencing stretching a compound bow string matches this definition.
For chemical potential energy: It is energy stored in the chemical bonds of atoms and molecules, released during reactions, which matches the option describing fuel, food, and batteries.

Answer:

1. For Elastic Potential Energy: When something is stretched or compressed within the object (for example, stretching a string of a compound bow).
2. For Chemical Potential Energy: Energy stored in the bonds between atoms and molecules, which is released during chemical reactions (e.g., fuel, food, batteries).
