How Does Force Affect Motion?

“How Does Force Affect Motion: Fighting Children’s Misconceptions with the ‘Fantastic Four’ Ways in Which Force Affects Motion” written by Gerald Darling is an article that can be found in National Science Teachers Association’s journal Science and Children. This article explains that it is important to identify students’ misconceptions about the topic before starting a new unit of study. The author suggests using a pre-assessment survey that includes a few questions to give the teacher an idea of what the students know or are unclear of. The author also explains their “Fantastic Four” ways of explaining forces affect on motion. He demonstrates this to his class outside using a tennis ball and a soccer ball. The fantastic four include: force changes an object’s speed, make an object move, stop an object, and change its direction. His demonstration of friction involves the students kicking a soccer ball on the grass and on the blacktop. He uses questioning to lead their thinking in the right direction. He then explains gravity by demonstrating a book dropped and a book sitting on a table. It is important to remember that students must understand these basic concepts of force and motion so they can later learn about other forces and more complex concepts. This is a great article to read to get a refresh on the basic concepts of force and motion or to get an idea of how to demonstrate these concepts to a class.
