PPT-Essential idea: Motion may be described and analysed by the use of graphs and equations.

Nature of science Observations The ideas of motion are fundamental to many areas of physics providing a link to the consideration of forces and their implication The kinematic equations for uniform acceleration were developed through careful observations of the natural world. Re-Made Version. Coupled Motion. Coupled motion problems are problems in which the movement of one object directly impacts the motion of another object.. We have already briefly covered this topic when talking about pulleys.. Kinematics Terminology. Scalar vs. Vector. Scalar: . quantities that have only a size, but no direction. i. e. : . distance, speed. Vector: . quantities that have a size and direction. ie. : . displacement, velocity. Kinematic Equations. Measuring Techniques. Assess. . Statements . 2.1.1 – . 2.1.5, . 2.1.7 – . 2.1.10. Due on Wednesday, . Oct. 29. Uniform Accelerated Motion. Acceleration:. .

Summary: The of a Quadratic Function is U shaped. . Positve. Equations for uniform acceleration. Where. s. is displacement (m). v. is the final velocity (m s. -1. ). u . is the initial velocity (m s. -1. ). a. is the acceleration (m s. -2. ). Equations of Motion for Constant Resultant Force. Also called ….. because………. …acceleration and resultant force are directly proportional. . s. uvat. equations. Also called ….. (unhelpfully). Motion graphs are an important tool used to show relationships between position, speed and time.. It’s an easy way to see how speed or position change over time. Distance vs. Time Graph. Shows an object’s position at a given time.. Sinusoidal Graphs. Sinusoidal Graphs. Periodic Function. Graphs of sine and cosine functions.. Functions whose graphs have a repeating pattern.. Period.
