What’s on the Work, Energy & Power poster
A 6-row table: Quantity · Formula · Unit.
The core relationships.
- Work — W = Fs cos θ — J
- Kinetic energy — Ek = ½mv² — J
- Gravitational PE — Ep = mgh — J
- Elastic PE — E = ½kx² — J
- Power — P = W/t = Fv — W
- Efficiency — useful ÷ total × 100 — %
A force perpendicular to motion does no work. Circular motion at constant speed involves a force and zero work.
Questions about the Work, Energy & Power poster
- What’s on the Work, Energy & Power poster?
- A 6-row table: Quantity · Formula · Unit. The core relationships. Work — W = Fs cos θ — J; Kinetic energy — Ek = ½mv² — J; Gravitational PE — Ep = mgh — J; Elastic PE — E = ½kx² — J; Power — P = W/t = Fv — W; Efficiency — useful ÷ total × 100 — %. A force perpendicular to motion does no work. Circular motion at constant speed involves a force and zero work.
- Who is the Work, Energy & Power poster for?
- Work, Energy & Power belongs to the Physics section rather than to a school year, because physical science is not something one grade owns. Anyone learning mechanics can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Work, Energy & Power poster?
- Work is force times distance in the direction of the force. The angle matters. A wall chart earns its place by being glanceable from where the work is happening, so Work, Energy & Power belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Work, Energy & Power?
- Circular Motion, Free Body Diagrams and Friction & Drag sit alongside Work, Energy & Power in the Physics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Circular MotionFree Body DiagramsFriction & Drag
- Is the Work, Energy & Power poster free to download and print?
- Yes. Work, Energy & Power downloads as a free PDF with no account, no email and no watermark, like everything else in the Physics section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Work, Energy & Power poster print at?
- Work, Energy & Power is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Work, Energy & Power loses nothing.Printing guide
