Study Notes

Elastic Potential Energy of a Spring

  • The formula for the elastic potential energy of a spring is 1/2kx^2, where k is the spring constant and x is the deformation.

Spring Constant

  • The spring constant (k) indicates the stiffness of a spring.
  • The units of the spring constant are N/m (newtons per meter).

Work and Energy Storage

  • When work is done to stretch or compress the spring, the work is stored as elastic potential energy.

Deformation 'x'

  • In the context of a spring, the deformation 'x' refers to the distance from the spring's equilibrium position.

Elastic Potential Energy Definition

  • Elastic potential energy of a spring is correctly defined as the energy stored in a spring when it is compressed or stretched.

Spring Stiffness and Spring Constant

  • A weak spring has a small spring constant, indicating less stiffness.
  • A stiff spring has a large spring constant, indicating more stiffness.

Units of Deformation 'x'

  • The units of the deformation 'x' are meters (m).

Stiffness and Potential Energy

  • A stiff spring stores more potential energy compared to a weak spring for the same deformation.

Term for Stiffness Property

  • The term that describes the property that tells you the stiffness of a spring is the spring constant (k).
