01

A good diagram
changes everything.

Before reaching for an equation, learn to see the interactions. Follow a short sequence from your first force diagram to a block on a slope.

LESSON · 8 MIN READ

Start with the force diagram

Choose an object. Find its interactions. Give every force a reason to be there.

02
LESSON · 10 MIN READ

Choose axes that do the work

A slope looks complicated until you choose a useful direction and resolve the weight.

A LITTLE EXTRA HELP

A few good resources.

Selected readings and a simulation, with a reason for each.
