Across
- 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.
Down
- 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
