This diagram covers Impulse and Force-Time Graphs within Impulse & Collisions for GCSE Physics. Revise Impulse & Collisions in Forces for GCSE Physics with 13 exam-style questions and 10 flashcards. Use this page as part of a wider topic revision path rather than treating it as an isolated fact. It is section 3 of 7 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.

📊 Impulse and Force-Time Graphs

Studio Render impulse and force-time graph on dark backdrop. Left: force-time graph with cyan axes, amber rectangular pulse (200 N from 0.5 s to 2.0 s), shaded area labelled AREA = IMPULSE, calculation 200 N x 1.5 s = 300 Ns. Right: impulse formulas panel F x t = change in p = m x change in v, variable key, units Ns or kg m/s. Bottom: safety application (longer time = smaller force) and worked example.
