In this lesson, we will learn how to solve problems on the motion of a system of two bodies suspended vertically by a string passing over a smooth pulley.

Lesson Plan

Students will be able to

apply Newton’s second law to solve problems involving a system of bodies and a smooth pulley,
calculate unknowns including acceleration and string tension,
calculate the force exerted on a pulley,
solve multistep problems including those where the string snaps.
