HS-PS2-1 Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
Clarification Statement: Examples of data could include tables or graphs of position or velocity as a function of time for objects subject to a net unbalanced force, such as a falling object, an object rolling down a ramp, or a moving object being pulled by a constant force.
Assessment Boundary: Assessment is limited to one-dimensional motion and to macroscopic objects moving at non-relativistic speeds.
This resource is explicitly designed to build towards this performance expectation.
Comments about Including the Performance Expectation
The simulation indicates the size of the forces by the length of the arrows on the free body diagram throughout the elevator ride. The learner can consider the lengths of those arrows and relate the individual arrows to the cause of that force. The Notes page that is included for student reading as well as the additional resources discuss the mathematical relationship between force, mass, and acceleration and names Newton’s second law of motion specifically.
