The objectives of this video are to introduce with the concept of impulse and momentum followed by a brief discussion on the relationship between impulse & momentum. First of all, the video clears the concept of impulse stating that impulse is the integral of forces with reference to time and then talks about the SI unit of impulse. Basically, in an impulse the relationship between force & time is inversely proportional. Next, the video discusses on the concept of momentum which is nothing but the product of mass and velocity & subsequently introduces the respective formula of momentum.
Moving on, the video correlates the momentum and impulse with each other successively deriving the equation of impulse in terms of the initial and final momentum. This yields the verity that linear impulse is equal to the change to an object linear momentum and this relationship allows to solve a problem related to impacts, forces and velocities. Overall, the video tries to give a brief inside to the impulse and momentum understanding which is must for the study of engineering mechanics.
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.
