Question

what is the formula for calculating the average velocity of a moving object? average velocity = \\( \delta d \times \delta t \\) average velocity = \\( \frac{\delta t}{\delta d} \\) average velocity = \\( \frac{\delta d}{\delta t} \\) average velocity = \\( \delta d + \delta t \\) question 17 1 pts the slope of a position - time graph can be used to find the moving objects velocity position acceleration none of the above

Explanation:

Step1: Recall the formula for average velocity

Average velocity is defined as the change in displacement ($\Delta d$) divided by the change in time ($\Delta t$). So, the formula is average velocity = $\frac{\Delta d}{\Delta t}$.

Step2: Analyze the position - time graph slope

The slope of a position - time graph is calculated as $\frac{\Delta y}{\Delta x}$. In a position - time graph, $y$ represents position (related to displacement) and $x$ represents time. So, slope = $\frac{\Delta \text{position}}{\Delta t}=\frac{\Delta d}{\Delta t}$, which is the formula for velocity.

Answer:

For the first question: average velocity = $\frac{\Delta d}{\Delta t}$ (the third option).
For the second question: velocity (the first option).
