What is Dynamics? Deals with the accelerated motion of a

body. Kinematics: which is treat only the

geometric aspect of the motion. Kinetics : which is the analysis of tye

force causing the motion. We will start with dynamics of

particlerigid-body.

An Overview of Mechanics

Statics: The study of bodies in equilibrium.

Dynamics:1. Kinematics – concerned with the geometric aspects of motion2. Kinetics – concerned with the forces causing the motion

Mechanics: The study of how bodies react to forces acting on them.

Tips to solve problems Mostly using calculus rather than algebra

and trigonometry.How to solve

problems?

Tips to solve problems Read the problem carefully and try to

correlate the actual physical situation with the theory you have studied.

Draw any necessary diagrams and tabulate the problem data.

Establish a coordinate system and apply the relevant principle generally in mathematical form.

Tips to solve problems Solve the necessary equations algebraically as

far as practical; then, use a consistent set of units and complete the solution numerically. Report the answer with no more significant figure than the accuracy of the given data.

Study he answer using technical judgement and common sense to determine whether or not it seem reasonable.

Tips to solve problems Once the solution has been completed,

review the problem. Try to think of other ways of obtaining the same solution
