Deep Dive IBDP Physics: - PHY D.1 Gravitational Fields Teacher Resource Pack

Understanding gravity is more than memorizing Newton’s Law—it's about seeing invisible forces and calculating the potential energy that governs planetary motion, satellite trajectories, and everyday phenomena. For educators teaching the IB Diploma Programme (IBDP) Physics, two essential concepts—gravitational field lines and gravitational potential energy—are foundational to the curriculum.

To support these learning outcomes, we present two classroom-ready resources:

  • Sketching Gravitational Field Lines

  • Gravitational Potential Energy Investigation

These hands-on, inquiry-based activities are aligned with IBDP Topic D.1: Gravitational Fields and give students a visual and analytical grasp of how mass shapes space and influences motion.


🌀 Resource 1: Sketching Gravitational Field Lines

Curriculum Alignment:

  • Topic D.1 – Gravitational Fields

  • Subtopics: Field strength, direction, visual representation of vector fields

What This Resource Covers:

Students explore how gravitational field lines depict the invisible force that attracts masses. Through collaborative sketching and analysis, they learn how to visualize and interpret field strength, direction, and equipotential surfaces.

Key Learning Objectives:

  • Understand characteristics of gravitational fields: lines point toward the mass and do not cross

  • Sketch field lines around a point mass and a uniform spherical mass

  • Interpret field line density as an indicator of gravitational strength

  • Label equipotential surfaces in relation to field lines

Activity Highlights:

  • Sketch gravitational fields around Earth and other spherical bodies

  • Use graphical tools or software to enhance visual understanding

  • Identify regions of strong vs. weak gravitational intensity

  • Present findings and justify reasoning to the class

Why It’s Effective:

  • Encourages students to move beyond equations and think visually

  • Reinforces the inverse-square law by examining line density

  • Supports spatial understanding and diagrammatic literacy

  • Stimulates class discussion and peer learning

Extend the Learning:

  • Simulate gravitational fields around binary star systems

  • Explore distortions near black holes

  • Connect field lines to concepts like gravitational potential wells.


⚖️ Resource 2: Gravitational Potential Energy Investigation

Curriculum Alignment:

  • Topic D.1 – Gravitational Potential Energy

  • Core Skills: Mathematical modeling, data analysis, graphing

What This Resource Covers:

This investigation takes a deeper dive into the relationship between gravitational potential energy (GPE) and distance from a mass, guiding students through real-world calculations and graphing to enhance conceptual understanding.

Key Learning Objectives:

  • Apply the formula:

    where UU is gravitational potential energy, GG is the gravitational constant, MM and mm are the masses, and rr is the distance from the center of the celestial body

  • Calculate GPE for varying distances from Earth or the Moon

  • Graph GPE vs. distance and analyze trends

  • Understand why GPE is always negative in gravitational fields

Step-by-Step Learning:

  • Choose a celestial body and define object mass

  • Calculate GPE at distances from RR to (e.g., Earth's radius to 3× Earth's radius)

  • Plot the energy values and interpret the inverse relationship

  • Discuss why energy becomes less negative with distance and its implications

Why Educators Love It:

  • Promotes real-life application of physics equations

  • Builds data literacy through graphing and interpretation

  • Reinforces the concept of work done against gravity

  • Connects to topics like satellite motion and escape velocity

Extend the Learning:

  • Apply GPE to satellite orbits and orbital energy balances

  • Model gravitational energy on other planets for comparison

  • Explore total mechanical energy in gravitational systems.


📚 How These Activities Support IB Physics Objectives

Both resources deliver rich, engaging learning experiences that fulfill the IBDP’s expectations for conceptual understanding, practical application, and critical thinking.

Skills Reinforced:

  • Visual modeling (field line sketching)

  • Equation application and algebraic manipulation

  • Graphing and interpreting real-world data

  • Peer collaboration and class discussion

  • Scientific presentation skills

Internal Assessment (IA) Potential:

  • Investigate how field line density changes with mass or distance

  • Model gravitational energy changes for hypothetical orbits

  • Analyze equipotential surface spacing and derive field strength patterns

  • Explore how gravitational potential relates to satellite design or interplanetary travel


Enhance your reach and visibility using relevant, high-impact tags:

  • IBDP gravitational field diagram activity

  • Gravitational potential energy vs. distance graph

  • Sketching gravitational field lines for physics class

  • Equipotential surface and gravitational field strength

  • Negative gravitational energy in orbital motion

  • Inverse-square law classroom activity

  • Celestial body gravitational modeling worksheet

  • Satellite GPE analysis IB physics


🌍 Help Students Grasp Gravity—From Theory to Application

These classroom-ready resources transform gravitational theory into something students can see, calculate, and internalize. With field diagrams and GPE calculations in hand, learners will deepen their understanding of how mass curves space, attracts objects, and governs celestial motion.

By adding these activities to your IB Physics repertoire, you give your students more than formulas—you give them the tools to visualize forces and quantify energy in the universe.
