DISTANCE - TIME GRAPHS

Understand motion with distance-time graphs! Practice interpreting speed, velocity, and rest.

Click on the correct words to fill in the blanks below. Speed can be calculated if you know the distance an object travels in one unit of time. Speed in a given direction is velocity.The steeper the graph, the faster the motion. A horizontal line means the object is not moving. A curved line means the speed is changing by speeding up or slowing down. This is acceleration. Matching distance-time graphs. Match the correct description to each graph. The speed of the car is decreasing. The car is stopped. The car is traveling at a constant speed. Describe the motion at point A Slow constant speed Increasing speed Stationary Fast constant speed Returning to start Describe the motion at point B. Stationary Increasing speed Slow constant speed Fast constant speed Returning to start Describe the motion at point C Stationary Increasing speed Slow constant speed Returning to start Fast constant speed Describe the motion at point D. Stationary Increasing speed Slow constant speed Fast constant speed Returning to start Describe the motion at point E Increasing speed Slow constant speed Fast constant speed Returning to start Stationary Which runner stopped for a rest? Albert Bob Charlie Which runner won the race? Albert Bob Charlie Every morning Tom walks along a straight road from his home to a bus stop, a distance of 160 meters. The graph shows his journey on one particular day.What is Tom’s average speed from 0 seconds to 50 seconds? 1 m 2 m 3 m 4 m What is Tom’s average speed from 70 to 100 seconds? 1 m 2 m 3 m 4 m Which statement matches what Tom did at 50 seconds? continued walking toward the bus stop started walking back home because he forgot something walked past the bus stop left his home to walk to the bus stop At what time did Tom reach the bus stop located 160 meters from his home? 0 seconds 50 seconds 70 seconds 100 seconds 120 seconds During what time interval on the graph was Tom at rest? 0-50 s 50-70 s 70-100 s 100-120 s he was never not moving During what time interval on the graph was Tom moving the fastest? 0-50 s 50-70 s 70-100 s 100-120 s What is Tom's total distance he traveled on his journey to the bus stop? 100 m 160 m 280 m What is Tom's total displacement he traveled on his journey to the bus stop? 100 m 160 m 280 m What was Tom's average speed to reach the bus stop? (Average speed =Total Distance Time you will need to calculate the distance covered for each segment divided by the time each segment of travel takes) 1.33 m 1.6 m 2.5 m 2.8 m
