Deep Dive IBDP Physics: - A.1 Kinematics Teacher Resources Pack

Understanding projectile motion is a cornerstone of kinematic studies in IBDP Physics, where students learn to analyze motion in two dimensions and explore the principles behind real-world phenomena like basketball arcs, long-jump trajectories, and even satellite launches.

To support educators in making these concepts come alive in the classroom, we’re excited to highlight two robust, hands-on, and curriculum-aligned resources:

• Activity 2: Horizontal Launch – The Physics of Projectile Motion

• Activity 4: Experimental Verification of Gravity's Influence on Projectiles

Together, these activities not only enhance conceptual understanding but also develop critical scientific investigation skills that are central to the IB philosophy.

🎯 Activity 2: Horizontal Launch – The Physics of Projectile Motion

Curriculum Link:

• IBDP Topic A.1: Equations of Motion in Two Dimensions

• Focuses on analyzing projectile motion, separating horizontal and vertical motion, and applying kinematic equations..

Learning Objectives:

• Calculate time of flight, horizontal range, and final velocity of horizontally launched projectiles

• Understand the independence of vertical and horizontal components

• Analyze motion using real-time measurements and data tables

Key Concepts Covered:

• Horizontal motion: Constant velocity (neglecting air resistance)

• Vertical motion: Constant acceleration due to gravity

• Combined motion analyzed using the equations:

  

How the Activity Works:

Students roll a small ball off the edge of a table, measure the height (y) and the horizontal distance (x), and use the time of flight to calculate the final velocity. They complete multiple trials, record data in tables, and identify patterns using equations and graphs.

Why It Works for IBDP:

• Brings mathematical models to life with real experimental data

• Encourages collaborative problem-solving and graphing skills

• Easily differentiated for both Standard Level (SL) and Higher Level (HL) learners

• Prepares students for data-based questions and IA design.

🧪 Activity 4: Experimental Verification of Gravity's Influence on Projectiles

Curriculum Link:

• IBDP Topic A.1: Independence of Motion Components

• Provides experimental verification that gravity acts only on vertical motion, a fundamental IBDP concept.

Learning Objectives:

• Demonstrate the independence of horizontal and vertical motion

• Prove that gravity does not influence horizontal velocity

• Compare vertical drop and horizontal launch experiments for consistency

What the Activity Involves:

Using two identical balls, students:

• Drop one ball vertically from a table

• Launch the other horizontally from the same height

• Measure time of flight and horizontal range

• Verify that both balls hit the ground simultaneously, regardless of horizontal velocity

Equations Used:

• Time of flight:

• 

• Horizontal distance:

• 

Why Educators Love It:

• Makes Newtonian principles visible through experiment

• Encourages scientific reasoning and error analysis

• Provides an excellent base for Internal Assessment (IA) extensions

• Builds deep conceptual understanding through repetition and reflection

🔍 Comparative Learning: How These Resources Work Together

Both resources are intentionally designed to reinforce each other:

When used together, students gain both the computational skills and conceptual frameworks needed to master projectile motion.

🧠 Extend the Learning

To deepen the impact of these lessons, consider these extensions:

• Video Analysis: Use slow-motion capture to visually confirm motion independence

• Graphical Modeling: Create velocity-time and position-time graphs for both motions

• Initial Velocity Exploration: Repeat the experiment with varying push strengths

• Link to Real-World Applications: Analyze sports (e.g., basketball, long jump), space launches, or stunts

🚀 Transform Theory Into Action with Engaging Projectile Motion Lessons

IB Physics isn’t just about mastering equations—it’s about seeing the world in motion and understanding the laws that govern it. With these two engaging, standards-aligned activities, students move beyond passive learning into the realm of scientific discovery, analysis, and reflection.

Whether you're introducing the fundamentals of two-dimensional motion or confirming Newton's insights through hands-on exploration, these resources equip you and your students with powerful tools for deep, meaningful learning.
