Cornell University: Cornell Center for Materials Research: Friction
A collection of experiments where students can learn about how friction works and affects the physical world. At the end, students design a tortoise to win by slowing it down using friction. Lesson includes explanation of the concept of...
Physics Aviary
Physics Aviary: Practice Problems: Work Done by Force With Friction
Students must determine the work done by a horizontal force when there is a frictional force acting on the box. Students must then find the speed of the box.
Physics Aviary
Physics Aviary: Practice Problems: Work Done by Force With No Friction
Students must determine the work done by a horizontal force when there is no friction acting on the box. Students must then find the speed of the box after this work has been added to the box.
Physics Aviary
Physics Aviary: Practice Problems: Work Done by Force on Angle With No Friction
Students must determine the work done by a force on an angle when there is no friction present between the box and the table. Students must also find the final speed of the box after this work has been added to the box.
