Effect of Young's Modulus on Elasticity:
Increased Young's Modulus leads to increased elasticity in a material. This relationship can be explained in detail below:

Definition of Young's Modulus:
Young's Modulus is a measure of the stiffness of a material. It quantifies how much a material will deform under a given amount of force.

Relationship between Young's Modulus and Elasticity:
- When Young's Modulus increases, the material becomes stiffer. This means that the material will deform less under a given amount of force.
- The increase in Young's Modulus indicates that the material can withstand higher stresses before deforming permanently.
- As a result, the material with a higher Young's Modulus will exhibit greater elasticity as it can return to its original shape more effectively after deformation.

Explanation:
- Think of a rubber band with a low Young's Modulus. When you stretch it, it deforms easily and may not return to its original shape completely.
- In contrast, a metal spring with a high Young's Modulus will deform less when stretched and will bounce back to its original shape due to its increased elasticity.

Conclusion:
- In summary, an increase in Young's Modulus enhances the elasticity of a material by making it stiffer, allowing for greater resistance to deformation and better ability to return to its original shape.
