constant speed, stopped, slowing down
speeding up, constant speed, slowing down
moving forward, stopped, moving backward
speeding up, stopped, moving backward
Which term refers to a change in velocity?
acceleration
speed
motion
momentum

a car traveling 33 km/hr speeds up to 42 km/hr
a car traveling 35 km/hr due north turns east while still traveling 35 km/hr.
All of these.
What is the acceleration of line B? Look at the line. Is the velocity changing?
A. 3.33 m/s/s
B. 0 m/s/s
C. 10 m/s
D. 10 m/s/s
A bus is traveling 20 m/s south. Is this speed or velocity?
A. Speed
B. Velocity
C. Acceleration
D. Motion
A plane is traveling 600 km/h. Is this speed or velocity?
Speed
Velocity
Acceleration
Motion
You ride your bike around the block at a constant speed of 11 km/h. What is changing?
Acceleration
Velocity
Both acceleration and velocity
Neither
Identify whether the following statements describe a change in acceleration.
A car stopped at a stop sign.
A boat traveling east at 10 knots.
An airplane traveling north 600 miles per hour.
A person running at 5 meters/second along a curving path.
This graph shows the velocity of a car.
a. Velocity is increasing, so the car is accelerating.
b. Velocity is decreasing, so the car is accelerating.
b. Distance is decreasing, so the car is accelerating.
d. Distance is increasing, so the car is not accelerating.
Emilee and Fred were both drawing motion graphs that had a horizontal (side to side) straight line. The straight line on Emilee's graph represents steady speed, and the straight line on Fred's graph represents stopped motion. Which of the following is true?
a. Emiliee's graph was a distance-time graph, and Fred's graph was a velocity-time graph.
b. Emiliee's graph was a velocity-time graph, and Fred's graph was a distance-time graph.
c. They were both drawing velocity-time graphs.
d. They were both drawing distance-time graphs.
Which of the following best describes an object's velocity?
a. A car travels 70 mph.
b. A boy runs near the school on a curvy path through the woods at a rate of 5 mph.
c. The airplane travels southeast at 283 mph.
d. The horse gets loose and runs generally northwest at a quick pace.
In science class, a group of students worked with a battery-operated car. The students recorded the time needed for the car to either travel 100 centimeters or to stop on each of three different surfaces. All other conditions in the investigation were kept constant. Trial 1 was on tile. Trial 2 was on wood. Trial 3 was on carpet. The students constructed the graph shown below. Which trial(s) showed constant velocity of the car for the total trial?
Trial 1
Trial 2
Trial 3
All three trials
The velocity of a school bus over the course of a trip is shown below. Which of the following is true about sections 1 and 3?
The acceleration during sections 1 and 3 are the same.
The positive acceleration during section 1 is faster than the negative acceleration during section 3.
The positive acceleration during section 1 is slower than the negative acceleration during section 3.
There is no way to know which section is showing a slower acceleration.
Which can occur when an object is accelerating?
a. It slows down.
b. It speeds up.
c. It changes direction.
d. All of the above
What is happening from 0 to 5 seconds?
a. The object is speeding up
b. The object is slowing down
c. The object is moving away from start at a constant speed
d. The object is sitting still
What is happening from 0 to 5 seconds?
a. The object is speeding up
b. The object is slowing down
c. The object is moving at a constant speed
d. The object is sitting still
Distance on y-axis and time on x-axis. What does the line represent?
A. the car is stopped
B. the car is traveling at a constant speed
C. the speed of the car is decreasing
D. All the above
Which interpretation describes the following graph?
Tom ran from his home to the bus stop and waited. He realized that he had missed the bus so he walked home.
Tom skateboarded from his house, gradually building up speed. He slowed down to avoid some rough ground, but then speeded up again.
Tom left his home for a run, but he was unfit and gradually came to a stop!
After the party, Tom walked slowly all the way home.
The rate at which velocity changes is called...
speed
time
direction
acceleration
Which is NOT an example of acceleration?
a car speeding up
a car hitting its brakes
a car going around a curve
a car going 55 mph on a straight road
Which of these ticker tapes illustrates slowing down?
1
2
3
4

a very large sphere.
constantly increasing its speed to stay in orbit.
