Linear Motion

4. A pure number that defines size.
6. A quantity with a magnitude but not a direction.
9. Any type of upwards or downwards motion that is constant.
12. When the instantaneous speed has the same value throughout its journey.
14. The measured or measurable period during which an action, process, or condition exists or continues.
15. The “steepness” of a straight line on a graph; the change in the y-variable divided by the change in the x-variable.
17. The speed and direction of a moving body after it has reached its maximum acceleration.

1. A defined origin and axes that specify the directions (N, S, E, W; left, right, up, down) in a problem.
2. The universal force of attraction acting between all matter.
3. A relative measurement of the path of an object compared to another.
5. The velocity of the object before the effect of acceleration.
7. A projectile motion in a horizontal plane depending upon the force acting on it.
8. A quantity that has both magnitude and direction.
10. The state of a body that moves freely in any manner in the presence of gravity.
11. The change in velocity per unit of time.
13. A place where someone or something is located or has been put.
16. The shortest line between two points.
