x = x₀ + v₀t + ½at²
x — displacement (m)
v = v₀ + at — velocity (m/s)
a — acceleration (m/s²)
slope of x-t = v · slope of v-t = a
v₀ · initial velocity3.0 m/s
a · acceleration2.0 m/s²
t · time2.0 s
x = x₀+v₀t+½at²— m
v = v₀ + at— m/s
a (constant)— m/s²
Key relationships
slope of x-t= v
slope of v-t= a
area under v-t= Δx
drag t to move ball
drag a to change motion
a=0 → straight line on x-t
Motion tab: watch the ball move. Drag a to change acceleration, v₀ to change starting speed, t to scrub through time.
