When answers are free, what is a teacher for?

Lecturing the same chapter for the eleventh year. Grading at midnight. Answering questions a search bar already answers. Hand that to the machine. Keep the part that made you a teacher — the question you didn't expect, the student stuck for the third time, the lesson you redraw on the way home.

Block on smooth incline, 30°. F_net = mg sin θ. So a = g sin θ ≈ 4.9 m/s².

Good — but you drew weight twice. Pick one frame and commit.

Module 2 · §3 · Newton's Second Law

F = ma.

But only in an inertial frame. Draw the bodies, name the forces, then reach for the formula — in that order.

Practice · problem 4 of 6

A 2 kg block on a smooth incline at 30°. What is its acceleration?

g ≈ 9.8 m/s²

g sin 30° ≈ 4.9 m/s²

g cos 30° ≈ 8.5 m/s²
