What expression represents the Velocity Equation?

• A. distance/time
• B. force x velocity
• C. mass x acceleration
• D. acceleration/change in time

Answer: (A)

Velocity is the rate at which position changes, so the expression distance divided by time, v = d/t, represents the velocity equation. It captures how far the object moves per unit of time, conveying both speed and direction in a straight-line context when using displacement. The other ideas mix in different concepts: force times velocity relates to power, mass times acceleration is Newton’s second law, and dividing acceleration by time isn’t a standard way to define velocity since acceleration already measures velocity change per unit time. So distance over time is the correct expression for velocity.
