What is Velocity in Physics?
Velocity is a fundamental vector quantity representing the rate of change of position over time, possessing both magnitude (speed) and direction.
In one dimension, average velocity is computed as displacement divided by the time interval.
Formula & Step-by-Step Calculation
v = Δx / Δt or s = d / t
Displacement divided by elapsed time.
Worked Step-by-Step Examples
Example 1
A sprinter runs 100 meters in 9.58 seconds. What is their average velocity?
Solution: 10.44 m/s (37.58 km/h or 23.35 mph)
• 100 m ÷ 9.58 s = 10.44 m/s
