Force Conceptual Questions
Q1. A book is lying at rest on a table. The book will remain there at rest because:
1) there is a net force but the book has too much inertia
2) there are no forces acting on it at all
3) it does move, but too slowly to be seen
1. A 500-kg elevator is pulled upward with a constant force of 5500 N for
a distance of 50.0 m. What is the net work done on the elevator?
2. Given a pendulum write its corresponding energies for points A, B, C, and D.

Extra Problems.
1. An elevator, suspended by a single cable, has just left the tenth floor and is speeding up
as it descends toward the ground floor. Identify the motion and a free body diagram. If
you are inside of the elevator, which one will you experi
