Formulas
What is the formula for final position minus initial position.
Δd=d2-d1
If the line on a position-time graph goes up in a straight line, what is happening to the object?
the object is moving at a constant speed
if a line on a graph is very steep what does that tells you about the rate of change
the rate of change is fast
what is the term for how fast an object is moving without considering its direction
speed
if you walk to school and it takes you 10 minutes what is this an example of measuring
time
What is the formula for velocity
V=Δd/t
if the line on a pt graph is flat what is happening to the object
the object is not moving
if a line on a graph is completely flat what does that mean about the data being measured
there is no change in the data
velocity
when you hit the brakes in a car what happens to your speed
your speed decreases
Formula for instants and intervals of time
Δt=t2-t1
if the line on a pt graph curves upward, what is happening to the objects speed
object is speeding up
if a lone on a graph curves upward getting steeper what does this mean about the rate of increase
the rate of increase is getting faster
what is the key difference between the speed and velocity
velocity includes direction while speed does not
if you run around a track and end where you started what is your displacement
zero
what is the pyramid formula for V=Δd/t
Δd / v * t
if the line on a pt graph goes down in a straight line what is happening to the object
object is moving backwards
if a lone on a graph slope downward what is happening to the values over time
the values are decreasing
if an object changes direction but keeps the same speed what happens to its velocity
velocity changes because the direction changes
when you ride your bike uphill and start to go slower what is happening to your speed
What is the pyramid formula for t=d over v
t = d/v
if the line on a pt graph starts to steep but then gets flatter what is happening to the object
object is slowing down
if a line on a graph starts steep but then flattens out what does that mean about the rate of change
the rate of change is slowing down
if an object is not moving what is its velocity
zero
if you throw a ball straight up what happens to its speed as it goes higher
speed decreases
