If you check out the physics curriculum at the Univ. of South Florida at this link ..
http://physics.usf.edu/data/babscurriculum-2016.pdf
you'll see that in the 1st two years the students takes 3 calculus courses, MAC 2281, 2282, and 2283. You can google the syllabuses for these courses and you'll discover that there is no coverage of differential equations at all.
Yet modern physics began with the differential equation F=MA, and since that time differential equations have been the language of physics. If you'll check this web page you'll see how the physics of point dynamics, electrical circuits, rigid body dynamics, heat transfer, the wave equation, stress and strain in materials, fluid dynamics, and electromagnet radiation, all start with differential equations, and depend on differential equation models.

Then you can see a series of videos where each of these topics is covered using Euler's method and the finite difference method, that is calculus based on the single formula distance equals velocity times time that is teachable in high school, here.
My conclusion is that we are teaching the wrong calculus first. By starting with computational calculus, in its simple forms Euler's method and the finite difference method which is Euler's method applied to partial differential equations, the student can start doing mathematical physics in high school, not as a junior in college. So, these are a resource for totally rewriting physics education, starting in high school.
