Differentiate elastic potential energy and chemical potential energy
Answers
Answer: Elastic energy is the energy store in a.. compacted spring; an extended elastic band; and a drawn bow.
Chemical potential energy is position of electrons in specific substance bonds that can be broken (energizes).
:
This stored energy is released and performs work when the elastic material reverts back to its original position. ... In comparison, chemical potential energy, is the energy released during the formation of chemical compounds.

Gymnasts often practice on foam floors, which increase the collision time when a gymnast falls. What effect does this have on collisions
The effect of the gymnast on the collision will increase. An elastic collision is when two bodies collide and separates after collision conserving the total kinetic energy before and after collision.

Change in gravitational potential energy of the chair is,
Explanation:
It is given that,
Mass of the chair, m = 12 kg
Distance of the second floor from the ground, h = 3.3 m
The position of ground at h = 0
Let is the change in gravitational potential energy of the chair. Initial potential f the chair is equal to 0.
or
So, the change in the gravitational potential energy of the chair is 390 joules.
Final answer:
The change in gravitational potential energy of the chair is +385 J.
Explanation:
The change in gravitational potential energy of the chair can be calculated using the formula ΔPE = mgh, where m is the mass of the chair, g is the acceleration due to gravity, and h is the change in height. In this case, the mass of the chair is 12 kg, the acceleration due to gravity is 9.8 m/s², and the change in height is 3.3 m. Plugging these values into the formula, we get ΔPE = (12 kg)(9.8 m/s²)(3.3 m) = 384.72 J. Therefore, the change in gravitational potential energy of the chair is approximately +385 J.
