Speed and velocity

Question

Speed and velocity

ScanSolve AI Tutor · Accepted Answer

Here's an explanation of speed and velocity based on the slide:

Define Speed.
Speed is the rate at which an object covers distance, regardless of direction. It is a scalar quantity, meaning it only has magnitude.
Define Velocity.
Velocity is the rate of change of displacement of an object in a given direction. It is a vector quantity, meaning it has both magnitude and direction.
State the difference.
Both speed and velocity describe how fast an object is moving. The key difference is that velocity includes the direction of motion, while speed does not.
Provide formulas.
The formulas for average velocity and average speed are:
Average velocity:
$\bar{v} = \frac{\Delta x}{\Delta t}$
Where $\bar{v}$ is average velocity, $\Delta x$ is displacement, and $\Delta t$ is the time taken.

Average speed:
$\bar{s} = \frac{d}{\Delta t}$
Where $\bar{s}$ is average speed, $d$ is distance, and $\Delta t$ is the time taken.
