Question

the area under a velocity-time graph represents
○ acceleration
○ displacement
○ instantaneous velocity
○ distance
○ average velocity

question 18 (1 point)
two hikers set out from the same spot and arrive at the same destination but they take different routes. which of the following quantities must be the same for both hikers?
○ distance
○ average speed
○ average velocity
○ displacement
○ acceleration

Explanation:

For the first question: The area under a velocity-time graph is calculated as velocity multiplied by time, which equals the change in position, or displacement.
For Question 18: Displacement is the straight-line distance from start to end point. Since both hikers start and end at the same locations, their displacement must be equal, even if their path distances (and thus average speed) differ.

Answer:

First question: displacement
Question 18: displacement
