Download Exam: Force and Motion 2011-2012 Standards Tested: 7 PSP 1

Exam: Force and Motion 2011-2012
Standards Tested:
7 PSP 1: Newton’s Laws of Motion describe the relationships among force, mass
and acceleration. Acceleration is the rate of change in speed, direction of motion,
or both.
7 PSP 2: The gravitational pull on an object is the object’s weight. Gravitational
forces are dependent upon a variety of factors.
