1. Nuclear Binding Energy and Stability – Determining the process that increases nuclear stability for different atomic nuclei. 2. Simple Harmonic Motion in Springs – Calculating the change in elastic potential energy for a system with varying force and stiffness. 3. Astronomical Distance Measurement – Identifying appropriate methods (parallax, redshift, or standard candles) for different celestial objects. 4. Damped Oscillations and Resonance – Analyzing how reducing damping affects the amplitude and frequency of a driven oscillating system. 5. Photoelectric Effect and Photon Energy – Evaluating the role of frequency and intensity in the emission of photoelectrons. 6. Gravitational Potential and Escape Velocity – Calculating the minimum speed required for a rock to travel from Earth to the Moon.
