LA.PS-M. Physical Science: Students will develop an understanding of the characteristics and interrelationships of matter and energy in the physical world.
GLE-E-8. Grade Level Expectation: Properties and Changes of Properties in Matter: Explain that gravity accelerates all falling objects at the same rate in the absence of air resistance (PS-M-B3)
PS-M-B1. Motions and Forces: describing and graphing the motions of objects. (1, 2, 3)
PS-M-B2. Motions and Forces: recognizing different forces and describing their effects (gravity, electrical, magnetic). (1, 2)
PS-M-B3. Motions and Forces: understanding that, when an object is not being subjected to a force, it will continue to move at a constant speed and in a straight line. (2, 3, 4)
PS-M-B4. Motions and Forces: describing how forces acting on an object will reinforce or cancel one another, depending upon their direction and magnitude. (1, 2)
PS-M-B5. Motions and Forces: understanding that unbalanced forces will cause changes in the speed or direction of an object's motion. (2, 4)
