When a moving object collides with a stationary object, the moving object slows down (its motion energy decreases) and the stationary object begins to move faster (its motion energy increases). Because the speed of the objects changes during a collision, this is evidence that the motion energy of the objects also changes. Energy is transferred from a moving marble to a stationary marble during a collision. The faster an object is moving, the more motion (kinetic) energy it has and the more motion (kinetic) energy can be transferred through collisions.<\/p>\n\n\n\n<div class=\"wp-block-columns wp-embed-aspect-16-9 wp-has-aspect-ratio is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><a href=\"https:\/\/bscs.org\/stella-elementary\/wp-content\/uploads\/sites\/29\/2025\/01\/Lesson-2-Teacher-Guide-final.pdf\" class=\"btn btn-button-full-color\">Teacher Guide<\/a><\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><a href=\"https:\/\/bscs.org\/stella-elementary\/wp-content\/uploads\/sites\/29\/2025\/01\/Lesson-2-Student-Handout-Final.pdf\" class=\"btn btn-button-full-color\">Student Handout<\/a><\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><a href=\"https:\/\/bscs.org\/stella-elementary\/wp-content\/uploads\/sites\/29\/2025\/01\/ET_gr4_L2_PPT.pptx\" class=\"btn btn-button-full-color\">PowerPoint<\/a><\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading wp-embed-aspect-16-9 wp-has-aspect-ratio\">Videos<\/h2>\n\n\n\n<div class=\"wp-block-columns wp-embed-aspect-16-9 wp-has-aspect-ratio is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-embed is-type-video is-provider-vimeo wp-block-embed-vimeo wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"SSUP_ET_L2_Parco_C2\" src=\"https:\/\/player.vimeo.com\/video\/1018007239?dnt=1&amp;app_id=122963\" width=\"500\" height=\"281\" frameborder=\"0\" allow=\"autoplay; fullscreen; picture-in-picture; clipboard-write\"><\/iframe>\n<\/div><\/figure>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\"><strong>ET Lesson 2<\/strong><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h3 class=\"wp-block-heading has-text-align-center\">Want more videos?
