Across
- 4. states that an object acted upon by a net force will accelerate in the direction of the force, and that the acceleration equals the net force divided by the object's mass
- 6. combination of all forces acting on an object
- 9. states that forces always act in equal but opposite pairs
- 10. gravitational force between an object an Earth
Down
- 1. - states that if the net force acting on an object is zero, the object will remain at rest or move in a straight line with a constant speed
- 2. two or more forces acting on an object that do not cancel, and cause the object to accelerate
- 3. a push or pull
- 5. two or more forces whose effects cancel each other out and do not change the motion of an object
- 7. force that acts to oppose sliding two surfaces that are touching
- 8. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
