- 2. s=d/t
- 3. for every action there is an equal and opposite reaction
- 7. the condition of a system when neither its state of motion nor its internal energy state tends to change with time
- 9. a force that keeps an object at rest
- 11. he international unit of measure for force
- 12. the sum of all the forces acting on an object
- 16. the total distance traveled by the object in a particular time interval.
- 21. the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object
- 22. a quantity that designates how fast and in what direction a point is moving
- 23. the location of an object at any given time
- 25. due to gravity the acceleration of a body in free fall under the influence of earth's gravity
- 27. a numerical measure of a line's inclination relative to the horizontal
- 29. rate at which velocity changes with time, in terms of both speed and direction
- 30. a force along the length of a medium, especially a force carried by a flexible medium, such as a rope or cable
Down
- 1. happens when an object decreases in length
- 4. he speed of an object at a particular moment in time
- 5. happens when an object increases in length
- 6. a force that resists the sliding or rolling of one solid object over another
- 8. an isolated system the total momentum of two or more bodies acting upon each other remains constant unless an external force is applied
- 10. a property of matter by which it remains at rest or in unchanging motion unless acted on by some external force
- 13. state of a body that moves freely in any manner in the presence of gravity
- 14. the force applied in one direction is greater than the force applied in the opposite direction
- 15. every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force
- 17. a quantity that has both magnitude and direction
- 18. an imperial unit of mass or weight measurement
- 19. any action that tends to maintain or alter the motion of a body or to distort it
- 20. product of the mass of a particle and its velocity
- 24. the forces acting on an object have equal strength and act in opposite directions
- 26. the speed of an object remains the same
- 28. the resistance created by any two objects when sliding against each other
