Public Release Items: Public release items have appeared on MSA forms and then are released for public viewing and use. Releasing items is one step to ensuring that schools, districts, and other stakeholders understand how the content standards are assessed on the MSA.

Standard 5.0 Physics

Topic A. Mechanics

Indicator 1. Develop an explanation of motion using the relationships among time, distance, velocity, and acceleration.

Objective c. Compare accelerated and constant motions using time, distance, and velocity.
