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, 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.
