The objective of this video is to introduce kinetics and to discuss Newton’s law. Basically, kinetics is used to analyze unbalanced forces and the changes to motion that they produce. At first, the video shows how to analyze the problems related to kinetic using the Newton’s second law of motion that states accelerations have caused when an object is subjected to forces. Next, the video talks about how kinetics uses this statement to solve different types of problems involving motion i.e., velocity, time of flight, displacement etc elaborating all the facts in greater details.
Second part of the video shows a comprehensive example of kinetics where it has asked to calculate the weight of bags based on the data given. The problem involves of bags that are being loaded onto a plane via steep ramp. A hydraulic ram at the bottom of the ramp brings the bags to rest in 150mm. It exerts a constant force of 2500N over this length. Moving on, the video step by step shows how to assess different values required to calculate down the weight of bags. At end, the video refers to do lot of practices to have better understanding on the procedures to solve problems relating kinetics.

Course Description
Mechanics, the study of forces and physical bodies, underpins a very large proportion of all forms of engineering. A thorough understanding of mechanics is essential to any successful engineer. This course helps develop an understanding of the nature of forces with consideration for how they may be simplified in an engineering context. The conditions of equilibrium are then used to solve a number of problems in 2D and 3D before moving on to a broad range of topics including centroids, distributed loads, friction and virtual work. The course will also provide an introduction to dynamics, with a particular focus on the effects that forces have upon motion.
