Measure velocity with a photogate. Calculate GPE at the top and KE at the bottom — and discover they're almost equal. The \"missing\" energy opens a conversation about friction and energy loss.\n\nWhat's Included:\n• Student worksheet with real setup photos, data tables, and calculation questions\n• Step-by-step lab instructions with photogate setup\n• Teacher notes with answer key and pacing guide\n• Print-ready digital resource + editable Word formats\n\nWorks with standard Vernier photogate. Designed for Grades 9-12 physics. NGSS-aligned. 50-75 minutes.\n\u003cdiv style=\"background:#ecfdf5;border:2px solid #059669;border-radius:12px;padding:16px 20px;margin:20px 0;text-align:center;\"\u003e\n\u003cp style=\"font-size:14px;font-weight:bold;color:#065f46;margin:0 0 6px 0;\"\u003e📦 Get the complete Motion unit\u003c\/p\u003e\n\u003cp style=\"font-size:13px;color:#374151;margin:0 0 10px 0;\"\u003eThis resource is part of the \u003cstrong\u003eMotion Unit Bundle\u003c\/strong\u003e — all lessons, labs, assessments, and review materials for the full unit.\u003c\/p\u003e\n\u003cp style=\"margin:0;\"\u003e\u003ca href=\"\/products\/high-school-physics-motion-unit-bundle\" style=\"display:inline-block;background:#059669;color:#ffffff;padding:10px 24px;border-radius:8px;text-decoration:none;font-weight:bold;font-size:14px;\"\u003eView the Motion Unit Bundle →\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n","brand":"Phantastic Physics","offers":[{"title":"Default Title","offer_id":48541217390821,"sku":null,"price":4.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0704\/4762\/8517\/files\/Energy_of_Motion_Thumbnail.png?v=1773265240","url":"https:\/\/phantasticphysics.com\/products\/energy-of-motion-lab-gpe-ke-conservation-photogate","provider":"Phantastic Physics","version":"1.0","type":"link"}
