(a) |
Pose and refine scientific questions about the ways in which forces cause objects to move or change their motion. (A, S) |
(b) |
Investigate the effects of applying constant forces to objects at rest and to objects moving at a constant velocity in a straight line. (S, A) |
(c) |
Add force vectors in one and two dimensions (i.e., collinear, non-collinear [perpendicular] and non-collinear [non-perpendicular]) using vector diagrams to determine the net force acting on an object. (S) |
(d) |
Demonstrate the role of friction in changing the position and/or motion of an object. (K, S) |
(e) |
Provide examples of technologies that have been developed to increase or decrease frictional forces between two or more surfaces. (STSE) |
(f) |
Analyze student-collected data to verify the relationship between the acceleration of an object and the net force acting on it. (S) |
(g) |
Describe and provide examples of Newton's three laws of motion in practical situations such as sports, flight and transportation. (K, A) |
