Across
- 4. is a vector quantity that describes how far an object move from its original position
- 8. determines if an objects move and in which direction
- 9. an object at rest stay at rest and an object in motion stays in motion unless acted upon by an unbalanced force
- 11. when a body moves in a fluid or in air then there exists a restive force which slows down the motion of the body
- 13. a place or object used for comparison to determine if an object is in motion
- 14. explains the behavior of an object
- 17. a force that pulls all object towards each other
- 18. equal forces acting on an object in opposite directions (no motion)
- 19. a push or a pull exerted on an object and described by its strength and direction in which it acts
- 20. the product of an object's mass and velocity
Down
- 1. an amount of space between two things
- 2. forces that produce a nonzero net force, which changed and object's motion (motion)
- 3. for every action, there is an equal and opposite reaction
- 5. the distance an object travels per unit of time
- 6. the overall rate of speed at which an object travels or moves
- 7. a force that slows down the motion of a rolling object
- 10. when a body is forced to move along a surface but movement doesn't not start (no motion)
- 12. is when a moving object increases speed, decreases speed or changes direction
- 15. occurs when two object slides over each other
- 16. speed in a given direction (speed with a direction)
