Physics Review

1. / have magnitude only.
5. / is displacement over total time.
6. / change in position.
9. / the position at a particular instant.
14. / the vector that represents the sum of the other two vectors.
15. / series of images showing the positions of amoving object at equal time intervals is called
16. / how far the object is from the origin.
17. / is the natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force.
18. / a simplified version of a motion diagram in which theobject in motion is replaced by a series of single points.
20. / the difference between two times

2. / is the absolute value of the average velocity.
3. / tells you the location of the zero point of the variable you are studying and the direction in which the values of the variable increase.
4. / Length, mass, time, electric current, thermodynamic temperature, amount of substance, luminous intensity.
7. / the separation between an object and the origin.
8. / have both magnitude and direction.
9. / the speed and direction of an object at a particular instant.
10. / descibes the nearness of a measurement to the standard or true value.
11. / rectilinear, curvilinear, angular.
12. / plotting the time data on horizontal axis and the position data on a vertical axis.
13. / the point at which both variables have the value zero.
17. / is the degree to which several measurements provide answers very close to each other.
19. / any movement or change in position or time.
