Distance Time Graphs - SC.6.P.12.1

(SC.6.P.12.1) Kalinda did an experiment to study motion. She then prepared the blank graph below to plot her results. Kalinda discovered that the object moved 20 meters (m) after 2 seconds (s), so she plotted her first data point as shown on the graph above. She also discovered that the object moved at a constant speed. Which of the following data points should Kalinda correctly plot next on her graph?

• 40 meters, 4 seconds
• 50 meters, 6 seconds
• 30 meters, 5 seconds
• 40 meters, 3 seconds

(SC.6.P.12.1) Remember that speed = distance / time. If an object is moving at a constant speed of 3 meters/second, how far will this object travel in 4 seconds?

• 6 meters
• 9 meters
• 15 meters
• 12 meters

(SC.6.P.12.1) The graph below plots the distance in kilometers traveled by an object over time in hours. What can you conclude from this graph?

• The speed of the moving object first increases and then decreases.
• The speed of the moving object increases over time.
• The speed of the moving object remains constant.
• The speed of the moving object decreases over time.

(SC.6.P.12.1) Juan decided to go sailing because the wind that day was blowing at a constant 15 miles per hour. The graph below plots the wind speed on a scale that scientists developed known as the Beaufort scale. According to this graph, what is the Beaufort scale number for the wind that Juan encountered when he went sailing?

• between 3 and 4
• between 4 and 5
• between 2 and 3
• between 1 and 2

(SC.6.P.12.1) Astronomers have discovered that not only is the universe expanding, but also that the expansion is accelerating. The graph below plots the speed of a galaxy versus the distance it has traveled.

• seconds (s)
• galaxy speed
• kilometers
• light-years

(SC.6.P.12.1) An asteroid is flying through space at a constant speed. Which statement below correctly describes the motion of the asteroid?

• Each day, the asteroid travels the opposite direction of the previous day.
• Each day, the asteroid travels the same distance it did the previous day.
• Each day, the asteroid travels farther than it did the previous day.
• Each day, the asteroid travels less than it did the previous day.

(SC.6.P.12.1) Kareem set up the materials shown in the illustration below as part of an experiment involving friction. What two instruments will Kareem need to calculate the speed of the book as it slides down the ramp?

• balance and stopwatch
• metric ruler and stopwatch
• metric ruler and balance
• magnifying lens and metric ruler

(SC.6.P.12.1) A marine biologist observed the swimming speed of five different types of fish as shown in the chart below. What measurements did the marine biologist take to correctly calculate the speed of these fish?

• distance and time
• volume and mass
• time and density
• distance and density

(SC.6.P.12.1) On a recent trip to the grocery store, Robert recorded the speed of the car every minute and then created the graph below. Look closely at the graph below which plots speed versus time. Which labeled line(s) on the graph represent periods of time when the car was moving at a constant speed?

• B and D
• A, B, C, and E
• only E
• A, C, and E

(SC.6.P.12.1) The graph below shows the constant running speed of four different animals. Which animals can have a constant speed that exceeds 40 miles per hour?

• cheetah, greyhound, and ostrich
• cheetah, quarter racehorse, greyhound, and ostrich
• cheetah, quarter racehorse, and greyhound
• cheetah, quarter racehorse, and ostrich
