Question de l’élève

Hello,

Maybe my question wasn't clear enough. Delta s is a y variable for position measured in meters. Why would some text books use Delta x instead? It's as if they are referring to the x axis.

Thanks

    Hi PeacefulPumpkin8091,

    In many physics textbooks, Δx is commonly used to represent displacement, especially in one-dimensional motion along the horizontal axis. However, Δs is a more general notation for displacement, often used when movement occurs in multiple dimensions or when referring to the magnitude of displacement rather than just a change along the x-axis.

    Some textbooks might use Δx instead of Δs because they assume motion is along the x-axis by default, especially when introducing kinematics. This can create confusion if position is typically represented on the y-axis in your textbook. However, it's mostly a notational choice, and both symbols can mean the same thing depending on the context.

    Hope it clarifies your question :)
