Elastic Strings & Springs (Edexcel A-Level Further Mathematics): Quizzes

$T = \frac{\lambda x}{l}$

The spring is less stretchy

Length when unstretched & not under tension

$x = \text{stretched length} - \text{natural length}$

Newtons ($\text{N}$)

Within the elastic limit

$0.2\text{ m}$

$40\text{ N}$

It returns to its original length

Tension in newtons ($\text{N}$)
