According to the text in the stimulus materials, Cosmonaut Gagarin’s pencil “obeyed Newton’s first law” and floated out of reach. Using Figures 1-3 in the stimulus materials, select the two statements that best explain Newton’s first law that affects the motion of the pencil. Select one or more: A. The force acting on an object is equal to the mass of that object times its acceleration. B. Motion cannot change without an unbalanced force acting. C. For every action, there is an equal and opposite reaction. D. An object at rest tends to stay at rest, and an object in motion tends to stay in motion, with the same direction and speed. E. The more force, the more the acceleration.
