## Learning Objectives

• Explain the concepts of position, velocity and acceleration for different kinds of motion. and be able to differentiate and integrate mathematical functions describing them.
• Be able to represent motion of an object using words, graphs, equations and motion diagrams. Learn to comfortably move between the different representations.
• Be able to identify and apply appropriate equations that describe motion in a given situation.
• Be able to apply a consistent methodology to solve problems.
• Be able to evaluate the reasonableness of an answer to a problem using dimensional analysis and special cases.
