Lesson: Average Speed Science

In this lesson, we will learn how to distinguish between constant speed and average speed.

Lesson Plan

Students will be able to

recall that the average speed of an object is the total distance moved by it over the total time taken to move,
use (the average speed formula) in all permutations,
recognize that the term nonuniform speed means that an object does not move equal distances in equal time intervals.

Lesson Worksheet

Q1:

If the speed of an object changes as the object moves, is the speed of this object uniform?

Q2:

A blue object and an orange object move across a grid of equally spaced lines. Both objects move for 4 seconds. The arrows show the distances moved each second. Which color object has greater average speed?

Q3:

A blue object and an orange object move across a grid of equally spaced lines. Both objects move for 5 seconds. The arrows show the distances moved each second. Which color object has a greater average speed?
