Unit 4 Force & Motion
SPS8. Obtain, evaluate, and communicate information to explain the relationships among force, mass, and motion.
a. Plan and carry out an investigation and analyze the motion of an object using mathematical and graphical models. (Clarification statement: Mathematical and graphical models could include distance, displacement, speed, velocity, time and acceleration.)
b. Construct an explanation based on experimental evidence to support the claims presented in Newton’s three laws of motion.(Clarification statement: Evidence could demonstrate relationships among force, mass, velocity, and acceleration.)
c. Analyze and interpret data to identify the relationship between mass and gravitational force for falling objects.
d. Use mathematics and computational thinking to identify the relationships between work, mechanical advantage, and simple machines.
