Across
- 7. is tendency of an object to resist change in its motion.
- 8. states that an object moves at a constant velocity unless an unbalanced force acts on it.
- 10. If gravity is the only force acting on an object, the object is said to be in
- 13. states that if no external forces act on a group of objects, their total momentum does not change.
Down
- 1. states that when one object exerts a force on a second object, the second object exerts a force on the first that is equal in strength and opposite in direction.
- 2. states that an object’s acceleration is in the same direction as the net force on the object and is equal to the net force exerted on it divided by its mass.
- 3. is a force exerted toward the center of a curved path.
- 4. is an attractive force between any two objects that depends on the masses of the objects and the distance between them.
- 5. is a friction-like force that opposes the motion of objects that move through the air.
- 6. is the maximum speed an object will reach when falling through a substance.
- 9. The gravitational force exerted on an object is the object’s
- 11. is a push or a pull
- 12. is the force that opposes the sliding motion of two surfaces that are touching each other.
- 14. the sum of all the forces acting on an object
