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.

Lesson Plan

Students will be able to

recognize that a distance can, but does not need to, correspond to motion in a straight line,
use the formula in all combinations,
distinguish between constant speed and average speed.

Lesson Worksheet

Q1:

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?

Q2:

What distance does an object with a speed of 15 m/s travel in a time of 4 seconds?

Q3:

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?
