Motion is one part of what physicists call mechanics. Everything in the universe displays some type of movement. In physics, motion is defined as a change in position of an object with respect to time. Scientists have discovered the major laws that explain the motion of objects. Unless they are living, objects do not change position on their own. Forces need to act upon an object to get it moving, or to change its direction or speed. The mass of the object and the magnitude and direction of the force are what ultimately determines how the object responds to an external force.Conceptual StrandObjects move in ways that can be observed, described, predicted, and measured.Guiding QuestionWhat causes objects to move differently under different circumstances?
Elements within this Standard
Grade Level Expectation
Recognize that the position of an object can be described relative to other objects or a background.
Design a simple investigation to demonstrate how friction affects the movement of an object.
Investigate the relationship between the speed of an object and the distance traveled during a certain time period.
Check For Understanding
Identify the position of objects relative to fixed reference points.
Design an investigation to identify factors that affect the speed and distance traveled by an object in motion.
Complete a coordinate graph to describe the relative positions of objects.
Plan and execute an investigation that demonstrates how friction affects the movement of an object.
Design and implement an investigation to determine that the speed of an object is equal to the distance traveled over time.
State Performance Indicator
Describe the position of an object relative to fixed reference points.
