STRAND 1: Forces & Interactions

Uniform motion of an object is natural. Changes in motion are caused by a nonzero sum of forces. A “net force” causes an acceleration as predicted by Newton’s 2nd Law. Qualitative and quantitative analysis of position, velocity, and acceleration provide evidence of the effects of forces.

STANDARD

LEARNING PROGRESSIONS

● I can describe changes in motion with words, graphically and mathematically. ● I can describe an object moving with a constant acceleration ● I can apply knowledge of acceleration to real world ● I can describe the effect of air-resistance on an object in freefall. phenomena including freefall.

Standard PHYS.1.1 Analyze and interpret data to determine the cause and effect relationship between the net force on an object and its change in motion as summarized by Newton’s Second Law of Motion. Emphasize one-dimensional motion and macroscopic objects moving at non-relativistic speeds. Examples could include objects subject to a net unbalanced force, such as a falling object, an object sliding down a ramp, or a moving object being pulled by a constant force. (PS2.A, PS2.C)
