GCSE Physics - Elastic Potential Energy and F = ke Equations #45
This video covers: - How to use the F = ke equation - What the spring constant k really means (how stiff the object is) - How to use the EPE = 0.5 k e^2 equation (EPE is elastic potential energy) - That the gradient of a force-extension...

Xylem and Phloem - Transport in Plants
"Plants have a transport system to move things around. The xylem moves water and solutes, from the roots to the leaves in a process known as transpiration. The phloem moves glucose and amino acids from the leaves all around the plant, in...

Khan Academy: Harmonic Motion: Harmonic Motion Part 2 (Calculus)
We test whether Acos(wt) can describe the motion of the mass on a spring by substituting into the differential equation F=-kx. [9:46]
