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

Objectives

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.

Prerequisites

Students should already be familiar with

distance.

Exclusions

Students will not cover

displacement,
velocity,
graphs.

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?
