Linear Motion

5. A relative measurement of the path of an object compared to another.
6. The state of a body that moves freely in any manner in the presence of gravity.
12. Any type of upwards or downwards motion that is constant.
17. The velocity of the object before the effect of acceleration.
18. A quantity with a magnitude but not a direction.
19. The “steepness” of a straight line on a graph; the change in the y-variable divided by the change in the x-variable.
20. The universal force of attraction acting between all matter.

1. A pure number that defines size.
2. A place where someone or something is located or has been put.
3. Equations that tell the relationship between initial and final velocity, displacement, time, and acceleration.
4. A projectile motion in a horizontal plane depending upon the force acting on it.
7. How “fast” an object travels; the distance an object travels divided by the length of time travelled; is a scalar.
8. The change in velocity per unit of time.
9. A quantity that has both magnitude and direction.
10. When the instantaneous speed has the same value throughout its journey.
11. The shortest line between two points.
13. A defined origin and axes that specify the directions (N, S, E, W; left, right, up, down) in a problem.
14. The measured or measurable period during which an action, process, or condition exists or continues.
15. The speed and direction of a moving body after it has reached its maximum acceleration.
16. An object’s displacement divided by the length of time travelled; is a vector; measured with the unit.
