All of these are ways to accelerate!
On a Velocity Time graph, a line showing zero acceleration (constant velocity) will be
straight and directed downhill line (A)
straight and directed uphill (lines B and D)
horizontal (line C)
vertical (not shown in the picture)
Speed is a ______ and velocity is a _______.
scalar; scalar
vector; vector
scalar; vector
vector; scalar
If you ignore air resistance, all object fall
at the same rate, -9.8 m/s2.
at different rates depending on their mass.
at different rates depending on their volume.
at the same rate, +9.8 m/s2.
A straight uphill line on a distance time graph (see picture) means
the object is not moving.
the object has a constant velocity.
the object is accelerating.
the object is moving backwards.
Which object is accelerating?
A car with cruise control on driving down a straight road.
Your sleeping dog.
Fan blades on a rotating ceiling fan.
A hovering helicopter.
Which requires a direction?
All scalars.
All vectors.
Only some scalars like time and distance.
Only some vectors such as acceleration and force.
As an object falls,
it keeps a constant speed.
it covers more distance each second.
it's acceleration increases.
it covers the same amount of distance each second.
As you run laps, your average speed decreases each time you go around the track. Because you are slower, each lap takes more time to complete than the previous one.
Your speed and time are ____ related.
directly
inversely
not
When the graph has a downhill slope (after 11 seconds),
the object has a constant acceleration.
the object is falling.
the object is moving forwards.
The object is moving backwards towards the starting point.
You can find the slope on a _______ graph to determine instantaneous velocity.
time on y axis, distance on x axis
distance on y axis, time on x axis
time on y axis, velocity on x axis
velocity on y axis, time on x axis
You can find the slope on a _______ graph to determine acceleration.
time on y axis, distance on x axis
distance on y axis, time on x axis
time on y axis, velocity on x axis
velocity on y axis, time on x axis
On a Velocity Time graph, a line showing negative acceleration will be
directed downhill line (A)
directed uphill (lines B and D)
horizontal (line C)
vertical (not shown in the picture)
Airplane #1 takes off from ATL and flies to NYC. Airplane #2 takes off from NYC and flies to ATL. Both travel at 700 km/h and take the same direct flight path. Which statement is true?
The airplanes have the same speed and velocity.
The airplanes have the same speed but different velocities because they have different magnitudes.
The airplanes have the same speed but different velocities because they have different directions.
the airplanes have different speeds and velocities because they have different magnitudes and directions.
What equation would you use to calculate how far a falling rock travels?
d = v * t
d = g * t
d = 1/2 g * t 2
d = g / t
Choose the velocity:
-9.8 m/s2
45 km East
5.6 m/s South
12.3 km/h
