Grade 5 Forces and Changes in Motion Big Idea 13 SC.5.P.13.1, SC.5.P.13.2, SC.5.P.13.3 & SC.5.P.13.4 Pacing Guide – Quarter 1 Topic 7 10/14-10/24 Keisha Kidd, Curriculum Support Specialist Mary Tweedy, Curriculum Support Specialist Millard Lightburn, District Supervisor Department of Mathematics and Science Office of Academics and Transformation Benchmark Objectives • SC.5.P.13.1 – Identify familiar forces that cause objects to move, such as pushes or pulls, including gravity on falling objects. AA • SC.5.P.13.2 – Investigate and describe that the greater the force applied to it, the greater the change in motion of a given object. AA • SC.5.P.13.3 –Investigate and describe that the more mass an object has, the less effect a given force will have on the object’s motion. • SC.5.P.13.4 –Investigate and explain that when a force is applied to an object but it does not move, it is because another opposing force is being applied by something in the environment so that the forces are balanced. 2 FORCE & MOTION What is MOTION? • Always a change in the position of an object. • Sometimes it may involve a change in direction, too. What changes motion? • Motion of an object changes when a force acts upon the object. • An object remains in motion, or at rest, unless a force acts on it. Object at rest Object in motion 5 What are forces? Gravity Friction Air Resistance A push or a pull Balanced Forces Versus Unbalanced Forces Types of Motion • • • • Move in a straight line. Move in a curved path. Move back and forth. Move at different speeds. Measurement Tools for Motion Speed • Distance (meter stick) • Time (stopwatch) Types of Forces • • • • Push or pull Friction Air Resistance Gravity What conditions can affect force and motion? • • • • Amount of mass Type of force applied Type of surface texture Surface area Moon Earth Factors that Determine Motion • Amount of force • Mass of the object • Change in speed (acceleration) Let’s Explore!
