Deep Dive IBDP Physics: - D.2 Electric and Magnetic Fields Teacher Resource Pack
The concepts of gravitational potential energy and orbital motion lie at the heart of celestial mechanics and space science—two areas that captivate students and align perfectly with the rigor of the IBDP Physics curriculum (Topic D.1: Gravitational Fields).
To help educators bring these abstract, space-bound concepts down to Earth, we've developed two powerful resources:
Gravitational Potential Energy Investigation
Orbital Motion Simulation
Each activity is carefully designed to blend conceptual understanding with mathematical application, offering students a hands-on journey through the invisible forces that govern planets, satellites, and spacecraft.
🌍 Gravitational Potential Energy Investigation
Curriculum Link: Topic D.1 – Gravitational Fields | Potential Energy in Fields | Mass and Distance Relationships
This engaging classroom activity guides students through the calculation and analysis of gravitational potential energy (GPE) in different gravitational environments. Through problem-solving, graphing, and paired discussions, learners build a deep understanding of how GPE varies with mass and distance—key to understanding everything from launching satellites to planetary escape velocities.
Key Learning Objectives:
Use the formula
U=−GMmrU = -\frac{GMm}{r}to calculate gravitational potential energy at varying distances
Understand why GPE is negative and how it approaches zero at infinite distance
Compare GPE across different celestial bodies (Earth, Moon, etc.)
Develop graphing skills to visualize GPE vs. distance
Activity Highlights:
Students select a celestial body and an object mass
Use structured tables to record GPE at different orbital radii
Graph GPE vs. distance to observe how energy changes non-linearly
Discuss how GPE relates to work done against gravitational forces
Benefits for Educators:
Encourages mathematical modeling and visualization
Deepens understanding of energy conservation in gravitational fields
Prepares students for advanced concepts in orbital mechanics and escape energy
Suggested Reflection Questions:
Why does GPE increase as an object moves further from a planet?
How does GPE differ on a small planet like the Moon versus Earth?
How is this concept crucial to understanding spaceflight and satellite motion?
Orbital Motion Simulation
Curriculum Link: Topic D.1 – Gravitational Fields | Centripetal Force | Orbital Dynamics
This resource uses interactive simulations (e.g., PhET’s “My Solar System”) to allow students to visualize and quantify orbital motion. Students explore how mass and distance influence orbital speed and period, seeing in real time how Newton’s Law of Universal Gravitation and centripetal force combine to shape the paths of satellites and planets.
Key Learning Objectives:
Explore how gravitational and centripetal forces govern orbits
Use the relationships:

Collect and graph orbital speed vs. distance and period vs. distance
Analyze Kepler’s Third Law in the context of simulation data
Activity Highlights:
Set up various simulations with stars, planets, and satellites
Alter mass and orbital radius to observe speed/period variations
Record and graph changes to detect patterns and verify formulas
Discuss real-world applications like GPS satellites and space probes
Benefits for Educators:
Makes orbital motion visual and interactive
Reinforces algebraic manipulation and equation derivation
Supports IA-style analysis and experimental design thinking
Suggested Student Questions:
How does doubling the orbital radius affect speed and period?
What would happen to orbital motion if gravitational force ceased?
How can simulations help predict satellite behavior in new systems?
