NGSS.3-PS. PHYSICAL SCIENCE
3-PS2. Motion and Stability: Forces and Interactions - Students who demonstrate understanding can:
3-PS2-2. Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion.
3-PS2.DCI. Disciplinary Core Ideas
PS2.A: Forces and Motion
PS2.A:1. Each force acts on one particular object and has both strength and a direction. An object at rest typically has multiple forces acting on it, but they add to give zero net force on the object. Forces that do not sum to zero can cause changes in the object’s speed or direction of motion. (Boundary: Qualitative and conceptual, but not quantitative addition of forces are used at this level.) (3-PS2-1)
PS2.A:2. The patterns of an object’s motion in various situations can be observed and measured; when that past motion exhibits a regular pattern, future motion can be predicted from it. (Boundary: Technical terms, such as magnitude, velocity, momentum, and vector quantity, are not introduced at this level, but the concept that some quantities need both size and direction to be described is developed.) (3-PS2-2)
PS2.B: Types of Interactions
PS2.B:1. Objects in contact exert forces on each other. (3-PS2-1)
