Crossword Puzzle

4. the distance an object travels per unit of time; speed = distance divided by time
6. the rate at which velocity changes; increasing speed, decreasing speed, or changing direction; (final speed minus initial speed) divided by time = acceleration
7. how much ground is covered by a moving object from start to finish
8. forces that produce a nonzero net force, causing an object to move, stop moving or change direction
13. If an object exerts a force on another object, the second object exerts a force of equal strength in the opposite direction on the first object; aka 'Action/Reaction Law'
14. the resistance that one surface or object encounters when moving over another.

1. the tendency of an object to resist any change in motion; is dependent upon the object's mass
2. An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force; aka 'Law of Inertia'
3. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
5. strength or energy as an attribute of physical action or movement.
9. equal forces acting on an object in opposite directions; results in 0 net force and no change in motion
10. The acceleration of an object depends on the object's mass and on the net force acting on the object; aka 'Law of Acceleration'
11. speed in a given direction; distance divided by time along with a stated direction
12. An object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram
