Acceleration is a fundamental concept in physics which is taught in mechanics at all levels. Here, we discuss some challenges in teaching this concept effectively when the path along which the object is moving has a curvature and centripetal acceleration is present. We discuss examples illustrating that both physics teachers and students have difficulty with this concept. We conclude with instructional strategies that may help students with this challenging concept.

Three derivations of the standard formula for the curvature K of a plane curve () yx are reviewed. Curvature is equal to 1 / r , where r is the radius of curvature, and is thus needed to compute theExpand

Problem Solving, Scaffolding and Learning.
Examining students’ problem solving abilities from different perspectives and investigating strategies that may guide students to develop a better knowledge structure in physics from the learners’ perspective suggests that postponing the providing of the solved problems until students have attempted to solve the quiz problems first without help is a good way to scaffoldStudents’ analogical problem solving.
