Senior Physics Challenge Past Papers [upd] · Genuine & Proven

This time, Mia finished the particle spiral problem. Jordan solved the circuit. And Priya derived the rocket equation so clearly that she could explain it to a younger student.

He drew three columns on the whiteboard, labeled: , Analyze , Adapt . Step 1: The Honest Attempt (No Fear, No Time Limit) Dr. Evans handed each of them a single question from a past paper: A rocket of mass m ejects gas at speed u. Derive its final velocity. senior physics challenge past papers

Jordan noticed something else. “Look at this—the first two marks are just for defining symbols and drawing a diagram. I skipped those. But they’re free points.” This time, Mia finished the particle spiral problem

Mia took a deep breath. She remembered Dr. Evans’ three columns. She wrote down what she knew. She drew the diagram. She took the first small step. He drew three columns on the whiteboard, labeled:

That’s when their physics teacher, Dr. Evans, who had been pretending to organize equipment, walked over. “Priya is right,” he said. “Most students use past papers as a test. But the wise ones use them as a tutor. Let me show you a method.”

Priya compared her attempted solution to the official one. “Oh! I forgot that the rocket’s mass changes continuously. That’s why they use calculus, not just simple momentum.”
