The graph shows the motion of three cars. Which statement BEST describes the motion of the cars?
Cars 1 and 3 have constant speeds, whereas Car 2 has a variable speed.
Cars 1 and 3 have variable speeds, whereas Car 2 has a constant speed.
All three of the cars have variable speeds.
All three of the cars have constant speeds.
Which of the following graphs BEST represents the motion of an object with increasing speed?
(Graph showing a straight line with positive slope)
(Graph showing a straight line with positive slope)
(Graph showing a curve upward)
(Graph showing a curve upward)
(Graph showing a straight line with negative slope)

Review the graph below, which plots total distance traveled versus time of travel for a moving object. Why do the values on the graph form a straight line?
The speed is constant.
The distance remains unchanged.
The direction of motion stays the same.
The speed gradually increases over time.
The graph below represents the relationship between the distance traveled and time elapsed for an object in motion. During which interval is the speed of the object changing?
AB
BC
CD
DE
Emily's mother told her she was "moving at a snail's pace." How could Emily determine the average speed of a snail?
She can subtract the snail's density from the time it takes for it to cover a set distance.
She could divide a set distance by the time it takes the snail to move that distance.
She could add together the times it takes the snail to cover several set distances.
She could multiply the snail's mass by the time it takes it to cover a set distance.
The driver of a car completes a trip. The graph displays data about the car's motion during the trip. CAR'S MOTION (Graph: Distance (meters) vs. Time (minutes)) Which of the following statements about the car's motion is true?
The total time for the car trip was 50 minutes.
The car returned to where it had started the trip at the end of the trip.
The car did not slow down during the trip.
The car did not travel at a constant speed during the entire trip.
How could the speed of a car be determined?
distance and time
distance and size
weight and time
weight and size
Select all of the ways that a person or object can accelerate:
Speed Up
Slow Down
Change Directions
Travel at a constant speed
Velocity can only be described by including both
speed and direction of the object in motion.
mass and direction of the object in motion.
speed and volume of the object in motion.
mass and volume of the object in motion.
