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.
Physics Aviary
Physics Aviary: Practice Problems: Work Done by Force (Force on Angle)
Students must determine the amount of work that is done by tension and the amount of work done by friction. Then students must find the work that turned into KE.
