What is the significance of the elastic limit in materials?

• The elastic limit is the temperature at which a material melts

• The significance of the elastic limit in materials is that it defines the point at which a material transitions from elastic to plastic deformation.

• The elastic limit is the maximum weight a material can hold

• The elastic limit is the point at which a material becomes transparent

Explain the concept of elastic potential energy.

• Elastic potential energy is the energy stored in an object when it is at rest.

• Elastic potential energy is the energy stored in an object when it is in motion.

• Elastic potential energy is the energy stored in an object when it is stretched or compressed.

• Elastic potential energy is the energy stored in an object when it is heated.

How is elastic potential energy related to the deformation of a material?

• Elastic potential energy is directly proportional to the deformation of a material.

• Elastic potential energy decreases as the deformation of a material increases.

• Elastic potential energy is inversely proportional to the deformation of a material.

• Elastic potential energy is not affected by the deformation of a material.

How does the stiffness of a material affect its elastic potential energy?

• Lower stiffness leads to higher elastic potential energy.

• Stiffness has no impact on elastic potential energy.

• Higher stiffness leads to higher elastic potential energy.

• Higher stiffness leads to lower elastic potential energy.

How can Hooke's Law be applied in real-life scenarios?

• By applying Hooke's Law to cooking recipes

• By utilizing Hooke's Law to improve smartphone battery life

• By understanding the relationship between force applied to a spring and its resulting extension or compression, Hooke's Law can be applied in designing mechanical systems like shock absorbers, mattresses, and medical devices.

• By using Hooke's Law to predict the weather
