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
