Quantities that incorporate both magnitude and direction
vectors
Quantities that only refer to magnitude
scalars
Name the trig angle
Sine
vx = vcosθ
where θ is the angle formed with the x-axis
equation for x component of a vector given a graph
vy = vsinθ
equation for y component of a vector given a graph
vector quantity referring to a change in location; the distance between where something starts and where it ends up, regardless of the path it took to get there
displacement
a vector quanity describing the change in displacement over time
SI: m/s
velocity
a vector quantity referring to the change in velocity over time
SI units: m/s2
acceleration
On a graph of displacement over time, the slope of a line is equivalent to…
Velocity
The area under the curve of a graph of acceleration vs time is
the change in velocity
The area under the curve of a graph of velocity vs time is
displacement
On a graph of velocity over time, the slope of a line is equivalent to…
acceleration
displacement = velocity x time
what is the rewritten form of the yellow equation
eqn in yellow highlight used when velocity is changing but we aren’t given a final velocity, only an initial one
eqn in orange used when we don’t know time and/or time is not a quantity the problem asks to solve for
Δx = vit+1/2at2
what is the rewritten form of the orange equation?
same eqn but 2aΔx (instead of 2ad)
