Elasticity and springs

• Explain that physically deforming an object (stretching, bending, or compressing) fundamentally requires the application of more than one concurrent force.
• Differentiate between elastic distortion (reversible) and inelastic distortion (irreversible).
• Calculate force, extension, or spring constant within the realm of linear elastic distortion using Hooke's Law.

$F = k \times x$

• Calculate the work done (energy transferred) during the elastic stretching of a spring.

$E = \frac{1}{2} \times k \times x^2$

• Differentiate visually and conceptually between linear and non-linear force-extension relationships.
• Investigate the relationship between applied force, subsequent extension, and overall work done when manipulating springs in a laboratory setting.
