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, graphs, or diagrams (vector diagrams) for objects subject to a net unbalanced force (a falling object, an object sliding down a ramp, an object being acted on by friction, a moving object being pulled by a constant force, projectile motion, or an object moving in a circular motion), for objects in equilibrium (Newton’s First Law), or for forces describing the interaction between two objects (Newton’s Third Law).
Assessment boundary: Assessment is limited to macroscopic objects moving at non-relativistic speeds whose measured quantities can be classified as either vector or scalar.
Note: this is a NYSED-specific performance expectation that is different from the Next Generation Science Standards.

NGSS Dimensions
Performance expectation HS-PS2-1 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Analyzing and interpreting data: Analyze data using tools, technologies, and/or models (e.g., computational, mathematical) in order to make valid and reliable scientific claims or determine an optimal design solution.
- Science models, laws, mechanisms, and theories explain natural phenomena: theories and laws provide explanations in science.
- Forces and motion: Newton’s second law accurately predicts changes in the motion of macroscopic objects.
- Cause and effect: Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects.
