What is the equation for velocity provided?

• A. P = F/A
• B. v = d/t
• C. a = dv/dt
• D. E = mv^2/2

Answer: (B)

Velocity is a rate of motion—the distance covered per unit time, including direction. The expression v = d/t directly captures that idea by dividing distance by the time taken, giving the average velocity with the appropriate units (such as meters per second). For example, covering 60 meters in 12 seconds yields 5 m/s. The other formulas describe different concepts: P = F/A describes pressure, a = dv/dt describes acceleration (how velocity changes over time), and E = mv^2/2 is kinetic energy (a value that depends on velocity but is not velocity itself). So the equation that directly gives velocity is v = d/t.
