1. Speed (v): Speed is the rate at which an object covers distance. It is a scalar quantity (has magnitude but no direction).
\[
v = \frac{d}{t}
\]
where \( v \) is the speed, \( d \) is the distance, and \( t \) is the time.
2. Distance (d): Distance is the total path covered by an object. It can be calculated if the speed and time are known.
\[
d = v \times t
\]
3. Time (t): Time is the duration over which the movement occurs. It can be calculated if the distance and speed are known.
\[
t = \frac{d}{v}
\]
