Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object & the mass of the object.||Next Generation Science Standards||Middle School||Physical Science||Motion and Stability: Forces and Interactions |||Construct & interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object & to the speed of an object. [Emphasis is on descriptive relationships between kinetic energy & mass separately from kinetic energy & speed.]||Next Generation Science Standards||Middle School||Physical Science||Energy |||Construct, use, & present arguments to support the claim that when the motion energy of an object changes, energy is transferred to or from the object.||Next Generation Science Standards||Middle School||Physical Science||Energy |||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, & its acceleration. [Objects subject to a net unbalanced force, e.g., an object falling , rolling down a ramp, or a moving- pulled by a constant force.]||Next Generation Science Standards||High School||Physical Science||Motion and Stability: Forces and Interactions|||Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system.||Next Generation Science Standards||High School||Physical Science||Motion and Stability: Forces and Interactions|||Develop & use models to illustrate that energy at the macroscopic scale can be accounted for as either motions of particles or energy stored in fields. [Examples: conversion of kinetic energy to thermal energy, the energy stored due to position of an object , & the energy stored between 2 electrically-charged plates. ] ||Next Generation Science Standards||High School||Physical Science||Energy|||Design, build, & refine a device that works within given constraints to convert one form of energy into another form of energy.||Next Generation Science Standards||High School||Physical Science||Energy
