## Important Topics for HC Verma Solutions for Class 11 Physics Chapter 14 – Some Mechanical Properties of Matter

Elasticity

Elasticity is the capability of an object to repel an altering effect and to return to its original size and shape when that effect or force is removed. Solid bodies will distort when acceptable forces are applied to them.

Stress

Stress is a physical quantity that describes the internal forces that neighbouring elements of a constant material applies to each other, while a strain is the measure of the distortion of the material.

Strain

When a body is exposed to a distorting force, a returning force happens in the body which is equivalent in magnitude but opposite in direction to the applied force. The strain is basically the measure of how much a body is stretched or distorted. A strain happens when force is applied to a body.

Hooke’s Law

Hooke’s law defines that the force required to extend or compress a spring by some distance (x) scales linearly in relation to that distance—that is, where k is known as the constant factor characteristic of the spring, and x refers to the small compared to the total possible deformation of the spring.

Fs = kx

Surface Tension

Surface tension is the tendency of liquid planes to shrivel into the least surface area possible. Surface tension permits insects, normally denser than water, to float and slide on a water surface.

Surface Energy

Surface energy measures the disturbance of intermolecular bonds that happens when a surface is produced. It is also known as surface free energy or interfacial free energy. In simple terms, surface energy can be described as the work per unit area completed by the force that generates the new surface.

Stokes’ Law

The law that the force holds back a sphere moving through a viscid fluid is directly proportional to the velocity of the sphere, the viscosity of the fluid, and the radius of the sphere. The law that the frequency of luminescence persuaded by radiation is generally less than the frequency of the radiation.
