Accepted Answer

$0\ \mathrm{km}$

Question 3

Which graph type is best used to visualize how an object's speed changes over time?

Accepted Answer

Velocity vs. time graph

Question 4

If the slope of a position vs. time graph increases, what does this indicate about the object's motion?

Accepted Answer

The object is speeding up.

Question 5

Which of the following equations correctly defines velocity?

Accepted Answer

$v = \frac{\Delta x}{\Delta t}$

Question 6

A runner moves rightward with a positive velocity. What does a negative velocity indicate?

Accepted Answer
