# Semester 1 Final Flashcards

speed

how fast the object is moving

velocity

speed in a given direction

position = _______________

(velocity)(time) + starting position

equation to find velocity

change in position over change in time

motion maps

represents position, velocity, acceleration, of an object at various clock readings

what do the dots represent on a motion map

the objects position each second and velocity is represented the arrow

acceleration

a change in velocity in a given amount of time

equation to find velocity

acceleration = velocity final - velocity initial over time

acceleration is a ______

vector that can be positive or negative

slope of a velocity time graph

acceleration

position time squared graph =

1/2 acceleration

velocity position graph =

2(acceleration)

acceleration due to gravity

9.8m/s2

free fall equations

Vf= gt

delta xy = 1/2gt2

Vf2= 2adeltax

vector

- arrow that show magnitude and direction
- length of arrow = magnitude
- point shows direction
