Collision in Two Dimensions Apparatus

Compare elastic and inelastic collisions in two dimensions

The Collision in Two Dimensions Apparatus gives students a hands-on way to investigate conservation of momentum and kinetic energy through real, measurable collisions. By comparing elastic, inelastic, and partially elastic collisions, students can see how mass, velocity, and collision type affect motion in two dimensions. The sturdy setup—featuring a curved aluminum track mounted on a flat metal base—supports repeatable experiments that bring abstract conservation laws into clear focus.

With its durable construction and thoughtfully chosen components—including a plumb line for alignment—the Collision in Two Dimensions Apparatus is an effective, classroom-tested tool for teaching core mechanics concepts with clarity and confidence.

Why Teachers Love the Collision in Two Dimensions Apparatus

• Clear comparison of collision types: Easily investigate elastic, inelastic, and partially elastic collisions side by side.
• Multiple ball options: Includes steel, glass, and hollow wooden balls to vary mass and elasticity.
• Two-dimensional motion: Curved track and adjustable target support enable authentic 2D momentum analysis.
• Designed for quantitative learning: Supports careful observation, measurement, and vector reasoning.
