Assuming that they do have a fixed shape to start with, when they are subject to heat or force. The forces could be compression, extension or deforming stress.

The relationship between energy and the shape of objects is that energy can change the shape of objects. When energy is applied to an object, it can cause the object to deform or change its shape. This can happen through processes like heating, stretching, or bending. The amount of energy applied and the type of energy can determine how much the shape of the object is altered.
The lens changes its shape by becoming more convex (thicker in the middle) when focusing on near objects. This shape change is controlled by ciliary muscles in the eye that pull on the lens to make it rounder, allowing for proper focusing on close-up objects.

Force
Group of objects that keeps it shape
Yes, a force applied to an object can deform its shape by stretching, bending, compressing, or twisting it. This change in shape is often temporary and depends on the magnitude and direction of the force applied.
Pressure could cause objects to deform.
The ciliary muscles surrounding the lens help it change shape to focus on objects at different distances. This process is known as accommodation, where the curvature of the lens is adjusted to bring objects into focus on the retina.
It is called deformation. This can occur through various processes such as stretching, compression, bending, or twisting, resulting in a change in the shape or size of the object.
Forces can stop or start an object in motion, or change its velocity. They can also change the shape of objects.
