Learning Activities
Last time, you have learned how to determine if an object is moving or not.
For this module, you will learn how motion can be visualized or illustrated using
tape charts and motion graphs. To help you get ready, perform the task

Read and analyze the following
statements and get ready to answer
the questions listed below:
A jeepney is moving at a rate of 45
kilometers within 0.50 hour before it
stops at a red light. After 5 minutes
the vehicle moves again, but this
time it initially moves at a rate of 15
kilometers for 15 minutes which then
increased to 35 kilometers after
another 15 minutes. The jeepney
then continued to move at the
same speed until it reaches another
