## Important Topics for DC Pandey Mechanics Part 1 Solutions Chapter 5: Laws of Motion

Pulley system

You have already studied the mechanism and functioning of the pulley system in your junior classes. In DC Pandey Laws of Motion Solutions, you will learn more about the combination of two pulleys combined in a single setup. You will also learn about the combination of a horizontal and a vertical setup.

Concepts of mass, velocity and force will also be utilized in understanding and solving different questions and cases related to pulleys. The fundamentals of the moment will also be used in some questions.

Motion In Different Directions

In this chapter, you will not only engage with the laws of motion but also the different directions in which force works to cause motion. You will get to engage with concepts of the moment, equilibrium, projectile motion, motion acting along the normal and motion in upward and downward directions. These directions will impact the force, displacement and angle of momentum with respect to the values and conditions that you will encounter in the questions.
