If Ms T wants to know her average speed walking from the bathroom to here, she should...

divide the distance she walks by the time

What is the speed formula?

d/t or distance divided by time

On a trip a car slows down and speeds up many times. In 4 hours the car travels 200 miles

200/4 would tell you the average speed

How is displacement different from distance?

Displacement is just concerned with how far (start to end)

What is the difference between speed and velocity?

velocity also includes direction

What does a horizontal line on a distance-time graph represent?

the object in question has stopped

Total length of a route. Like 4 times around a track=4 laps

Which is an example of constant speed?

The car moved at 50 m/s for the last 3 minutes.

Which is an example of instantaneous speed?

At this exact moment Feta is moving his head 5 m/s

Answers

1
What tells you that the red line has a greater speed?
it is on top of the blue line
it is higher
red is always greater than blue
steeper slope
2
If Ms T wants to know her average speed walking from the bathroom to here, she should...
Impossible, she always stop to talk to Ms. Perry
divide the time by the distance she walks
multiply the distance she walks by the time
divide the distance she walks by the time
3
What is the speed formula?
a2+b2=c2
dt or distance times time
t/d or time divided by distance
d/t or distance divided by time
4
In what ways can an object change speeds?
speed up or slow down
back and forth
speed up or go faster
slow down or slower down
5
How can we tell an object has changed it's position?
compare to a reference point
just look at it
record it
no way to tell
6
A car is going at a constant speed of 50 m/s. What do you need to know its velocity
average speed
direction
speed
where it started
7
Which units do we use in science to measure speed?
miles and hours
meters and seconds
minutes and inches
meters and sickens
8
A car passes by a police officer with a radar gun. What is the cop measuring?
average speed
constant speed
instantaneous speed
velocity
9
On a trip a car slows down and speeds up many times. In 4 hours the car travels 200 miles
200/4 would tell you the constant speed
200/4 would tell you the instantaneous speed
4/200 would tell you the average speed
200/4 would tell you the average speed
10
Where should the time be on a distance-time graph?
On the "y"
On the top
On the "x"
On the side
11
Where should the distance be on a distance-time graph?
On the top
On the "x"
On the bottom
On the "y"
12
When you see a horizontal line on a distance-time graph, what can you tell about its speed?
the speed is zero
the object is slowing down
speed is remaining constant at whatever it was going before
the object is going in the opposite direction
13
How is displacement different from distance?
They are the same
Displacement also account for how far up you travel
Displacement is just concerned with how far (start to end)
Displacement is total distance-like 4 times around= 4 laps
14
What is the difference between speed and velocity?
they both use meters per second
velocity also includes direction
speed also includes direction
velocity changes, speed stays the same
15
What does a horizontal line on a distance-time graph represent?
That the object is dead
the object in question has stopped
That the object is changing position
That the object is slowing down
16
What is involved with motion?
change in orientation
change of diaper
a change in position
change in direction
17
A man walks all the way around a square path. His distance is 100 m. What is the displacement?
zero m
400 m
50 m
100 m
18
What does the picture show
the pancake recipe
the velocity formula
the speed formula
the wrong formula for speed
19
A Feta travels 9 meters in 3 seconds. What is its speed?
27 m/s
9 m/s
3 m/s
6 m/s
20
What is distance?
How much something weighs
Total length of a route. Like 4 times around a track=4 laps
How far you are from start. Like 4x around a track=1 lap
What makes the heart grow fonder
21
Which is an example of constant speed?
At this exact moment the car is moving at 50 m/s
The car moved at 50 m/s for the last 3 minutes.
The car was moving at 50 m/s but then accelerate to 60 m/s
The car was moving at an average of 50 m/s
22
Distance divided by time equals ________
velocity
mph
speed
headache
23

8 m/s
10 m/s
20 m/s
5 m/s
24
All matter is constantly ___________
floating
spinning
in motion
moving up and down
25
Which is an example of instantaneous speed?
Trick question. Feta never moves
Feta moves his head about 1 meters every 60 seconds
At this exact moment Feta is moving his head 5 m/s
Feta is moving his head at a constant speed of 5 m/s
