Lesson: Speed Physics • 9th Grade
In this lesson, we will learn how to find the speed as a rate of change of distance that objects move during a time interval.
A car takes some time to travel from one end of a stretch of road to the other end, and the ends of the stretch of road are 540 m apart. The car travels along the stretch of road at a constant speed of 36 m/s. How much time does it take for the car to reach the other end?
What distance does an object with a speed of 15 m/s travel in a time of 4 seconds?
The sides of a baseball diamond are 27 m in length. What is the average speed of a baseball player who runs from first base to third base in a time of 7.2 s?
