Understanding the Difference Between Acceleration and Velocity in High School Physics

Understanding the Difference Between Acceleration and Velocity in High School Physics

What is Velocity? In high school physics, velocity is one of the fundamental concepts students encounter. It is defined as the rate of change of an object’s position, or displacement, over time. Mathematically, velocity is expressed as: v = Δx / Δt Where: Velocity is a vector quantity, meaning it has both a magnitude (speed) and direction. For instance, if a car moves 100 meters east in 10 seconds, its velocity is: v = 100 m / 10 s =…
