Develop some basic understanding of differentiation and integration. (Will be useful when dealing with questions involving variable acceleration)<br \/>3. Learn about the position vs time, velocity vs time, and acceleration vs time graphs<br \/>4. Understand how equations of one dimensional motion with particle moving at constant acceleration can be derived from velocity vs time graph or from the definition of instantaneous velocity and acceleration<br \/>5. Practice good amount of questions on one dimensional motion. I would recommend that you understand how different questions are asked on one dimensional motion (there are essentially 9 different types of questions) and practice questions for each of the question type.<br \/>6. Once you become comfortable with one dimensional motion, you will learn about vectors, which is essential to describe motion in two dimensions. Here, you should get comfortable with graphical representation of vectors and vector algebra (note: scalar\/dot and cross\/vector products will be important in the chapters to come).<br \/>7. Practice good amount of questions on vector algebra. Note that there are primarily 3 types of questions that can be asked on vectors in physics paper<br \/>8. Moving on to 2 dimensional motion, you should now be able to apply definitions of instantaneous velocity and acceleration learnt in one dimensional motion along with 1D kinematic equations for constant acceleration to 2D motion. And given $x(t)$, $y(t)$ and $z(t)$, you should be able to determine velocity, $\\overrightarrow{v}(t)$, and acceleration, $\\overrightarrow{a}(t)$ vectors. Or given, constant acceleration $\\overrightarrow{a}$, you should be able to determine $\\overrightarrow{r}(t)$<br \/>9. Now you are ready to dive in projectile motion, where in a particle is thrown at an angle from the horizontal, with gravitational acceleration $g$ in vertical direction and no acceleration in the horizontal direction, wherein, there are 15 different types of questions that you should be aware of.<br \/>10. Towards the end, you need to learn the concept of relative velocity, where you will have to determine position or velocity of one particle with respect to other. $\\overrightarrow{r}_{BA} =$ $\\overrightarrow{r}_B &#8211; \\overrightarrow{r}_A$ and $\\overrightarrow{V}_{BA} = $ $\\overrightarrow{V}_B &#8211; \\overrightarrow{V}_A$, where $\\overrightarrow{r}_{BA}$ is the position of $B$ with respect to $A$ and $\\overrightarrow{V}_{BA}$ is the velocity of $B$ as seen by $A$. Do go through the 12 different types of questions on relative motion.<\/p><p>Now let&#8217;s look at some of the commonly asked questions on Kinematics<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-6c4f505 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"6c4f505\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-ee16476\" data-id=\"ee16476\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-9fab363 elementor-widget elementor-widget-heading\" data-id=\"9fab363\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Frequently asked questions<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-3ad2bc9 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"3ad2bc9\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-1c859d7\" data-id=\"1c859d7\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap\">\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Kinematics, study of motion, is fundamental to other chapters in physics. &#038;
