MCQ
Which of the following is the correct formula for average velocity?
- A$\text{v}=\frac{\text{dx}}{\text{dt}}$
- ✓$\text{v}=\frac{\text{x}}{\text{t}}$
- C$\text{v}=\text{xt}$
- D$\text{v}=\frac{\text{t}}{\text{x}}$
✓
Answer
Correct option: B.
$\text{v}=\frac{\text{x}}{\text{t}}$
$b.$ $\text{v}=\frac{\text{x}}{\text{t}}$
Explanation:
The correct formula is $\text{v}=\frac{\text{x}}{\text{t}}.$ Average velocity is total change in displacement divided by total change in time. $\text{v}=\frac{\text{dx}}{\text{dt}}$ is the formula for instantaneous velocity.
