Physics Unit 1 Part 1 Retake Flashcards
Distance
how far an object travels over a certain time interval
Ex: path on roads, gap
Displacement
a straight line distance and direction between two positions
change in X
Position
where an object is located, relative to a coordinate system (some arbituary reference point)
Ex: location, point, place
Velocity (v)
tells you how fast and the direction
Velocity average
change in x / change in t
Speed
tells you how fast
Speed average
total distance / change in t
how to calculate distance
add the length of each side (no direction)
displacement formula
Final x - Intial x
slope of p vs t graph
velocity (m/s)
slope of v vs t graph
constant velocity, acceleration (m/s/s) (m/s^2)
y-intercept of p vs t graph
initial position
y-intercept of v vs t graph
initial velocity
Area of p vs t graph
no meaning
Area of v vs t graph
displacement (change in x)
average vs instantaneous
average is overall and instantaneous and is at a certain point
P vs t math model
position = velocity (time) + initial position
(x = vt + x0)
v vs t math model
velocity = acceleration (time) + initial velocity
(v = at + v0)
