Unit 3: Constant Velocity Flashcards
Displacement
How far an object has moved relative to its starting point
vector
Distance
how far an object moved (no direction, so can’t be negative)
always in a straight line
velocity
rate of change (aka the slope) of displacement
speed in a specific direction

To solve for resultant forces we use the ____
pathagreoum theorum
standard postion is…
the initial side of the angle is on the positive x-axis.
resultant vector is
equal to the sum of two or more vectors.
why are vectors used in physics?
to visually represent acceleration, velocity, and position
what does it mean to move at a constant rate
you never accelerate and never slow down
Position
where something is at any particular time
scalar quanitity
a quanitity only described by magnitude
instantanous speed
speed of an object in that particular moment
average speed
the total distance traveled by smthing in a particular interval
