Construct appropriate graphs from data and develop qualitative statements about the relationships between variables. Communicate the steps and results from an investigation in written and verbal presentations. Recognize whether evidence is consistent with a proposed explanation. How levers confer mechanical advantage and how the application of this principle applies to the musculoskeletal system. Problem Solving Motion Position is defined relative to some choice of standard reference point and set of reference directions.
Average speed is the total distance traveled divided by the total time elapsed.
The speed of an object along the path traveled can vary. Solve problems involving distance, time, and average speed. Changes in velocity can be changes in speed, direction, or both. Interpret graphs of position versus time and speed versus time for motion in a single direction. Site License Problem Solving Forces Force direction and magnitude.
