Motion, Forces, Energy — Dual View
Motion can be modeled precisely with algebra and graphs.
Creation’s predictability reflects Yahuah’s faithful order (Psalm 19:1).
Why is motion everywhere governed by the same math relationships?
A car starts at rest and accelerates at 3 m/s² for 4 s. Find v and Δx.
Vector decomposition solves real-world motion (sports, engineering, ballistics).
Orderly motion and predictable trajectories reflect design, not chaos.
Launch: v₀=20 m/s at 30°. Find v₀x, v₀y.
Laws emerged from observation and mathematics.
The consistency of these laws reflects the faithful character of the Creator (Heb. 1:3).
Why do these laws hold everywhere and every time? Chance cannot guarantee universality.
FBDs are the universal language for solving mechanics problems.
Forces obey consistent laws—evidence of a consistent Lawgiver.
Draw a free-body diagram for a block on an incline with friction. Solve for acceleration:
Gravity explains planetary orbits, tides, and satellite motion with one equation.
“He stretches out the north over empty space, and hangs the earth upon nothing.” (Job 26:7) — gravity displays His sustaining power.
Gravitational constant G is finely tuned; small changes would make stable orbits impossible.
Find centripetal acceleration for v=10 m/s, r=5 m. m/s²
