End of Semester Exam Physics - 1st 2023

Chapter 9.1 - 11.0

Motion

change in position

Frame of reference

Is the perimeter in wich an observer can see motion

Distance

size of displacement between 2 points

Displacement

lenght between 2 points as a straight line

* Its a vector

Distance traveled

total lenght that you travell between 2 points

Direction

orientation of a point regarding to another

Speed

how fast or slow an object travels over time

* speed = distance/time
* constant or variable
* instantaneous speed

Position vs Time Graph

* velocity = d2-d1 : t2-t1

Velocity

the measure of speed and direction

* m/s
* velocity = displacement/time

Acceleration

the rate at whitch velocity changes
