Momentum and Collisions gives Grade 7 science students focused practice with momentum, conservation of momentum, collision types, and contact forces within the context of motion and stability. Students connect mass and velocity to momentum and use simple collision situations to interpret how motion changes.

Core Physics Concepts

The resource builds understanding of how mass and velocity determine momentum and how total momentum can remain the same during a collision when outside forces are small. Students also distinguish between elastic and inelastic collisions, including situations where objects stick together after impact.

Collision interactions provide another opportunity to examine forces. Students explain how two colliding objects exert forces on one another and how those contact forces change motion.

Practice That Connects Ideas to Calculations

The worksheet begins with an informational reading passage that introduces momentum, conservation of momentum, elastic and inelastic collisions, and contact forces. Students then apply those ideas through multiple-choice questions involving momentum calculations, collision outcomes, mass and velocity comparisons, conservation of momentum, and interacting forces.

Additional activities include true-or-false statements, short-answer responses, a labeled diagram, a categorization activity, and a short note. Short-answer prompts ask students to explain how mass and velocity affect momentum, describe what happens to total momentum during collisions with small outside forces, and explain how contact forces change motion.

Designed for Flexible Grade 7 Science Instruction

Use this momentum worksheet as guided practice after instruction, independent classwork, review of forces and interactions, or reinforcement before moving to more complex collision problems. The combination of reading, calculation, conceptual questions, and written explanations gives students several ways to demonstrate their understanding of the same core physics ideas.
