Forms? Tag it!

Avoid using timer. Instead, use the separate thread, update the coordinates periodically with some delay using System.Threading.Thread.Sleep and notify UI thread using System.Windows.Forms.Control.Invoke or BeginInvoke. To make is smooth, use real time for calculation of coordinate in each iteration using System.DataTime.Now or System.Diagnostics.Stopwatch.

About invocation:

You cannot call anything related to UI from non-UI thread. Instead, you need to use the method Invoke or BeginInvoke of System.Windows.Threading.Dispatcher (for both Forms or WPF) or System.Windows.Forms.Control (Forms only).

You will find detailed explanation of how it works and code samples in my past answers:
Control.Invoke() vs. Control.BeginInvoke()[^],
Problem with Treeview Scanner And MD5[^].

See also more references on threading:

Control events not firing after enable disable + multithreading[^].

Now, maybe you don't need PictureBox at all. I'm not sure it helps you. You can animate things directly using custom Control. This is how:
