I'm learning about Hooke's law and modulus of elasticity (also known as youngs modulus) but it seems I am being taught it differently in maths and physics.
In maths I am taught that T=λx/l and λ is the modulus of elasticity, measured in newtons.
In physics I am taught that T=λAx/l where λ is measured in Pascals.
What's going on?
Just to clarify, T is the tension in the spring, x is the extension, l is the natural unstretched length of the spring and A is the cross sectional area.
