1. Homework Statement
Three objects can only move along a straight, level path. The graphs below show the po sition d of each of the objects plotted as a function of time t.
The magnitude of the velocity ∥⃗v∥ of the object increases in which of the cases? (view image/attached file)
2. Homework Equations
3. The Attempt at a Solution
I thought the correct answer was graphs 1 and 3 because the distance in graphs 1 and 3 changes over time. Therefore, the velocity must be increasing over time. However this answer is not correct.
