Graphs & Data Interpretation — A/L Physics

How do I practise Graphs & Data Interpretation?

1 question with a worked solution

1. In a rectilinear motion experiment with uniform constant acceleration a and initial velocity u, a graph of v² against displacement s is plotted. What do the gradient and intercept on the vertical (v²) axis represent?
   1. A) Gradient = a, Intercept = u
   2. B) Gradient = a/2, Intercept = u²
   3. C) Gradient = 2a, Intercept = u²
   4. D) Gradient = 2a, Intercept = 2u
   Check my answer

   Correct answer: C) Gradient = 2a, Intercept = u²

   From the kinematic equation v² = u² + 2as, comparing with the linear equation y = mx + c (where y = v² and x = s) shows that the gradient m = 2a and the y-intercept c = u².

   Show worked solution

   Step 1: Write kinematic equation: v² = 2as + u². Step 2: Match with y = mx + c: y = v², x = s. Step 3: Gradient m = 2a; y-intercept c = u². Answer: Gradient = 2a, Intercept = u².
