Exploring Reading Speed Graphs

The video tutorial covers motion graphs, focusing on speed, distance, and time. It explains how to interpret speed graphs, identifying constant and variable speeds through graph lines. The tutorial also includes practice questions to reinforce understanding of graph interpretation and speed calculations.

What are the two main variables involved in calculating speed?

• Distance and Time

• Speed and Velocity

• Acceleration and Time

• Distance and Velocity

Why is time considered an independent variable in motion graphs?

• Because it is measured in seconds

• Because it depends on speed

• Because it is always constant

• Because it can change based on distance

What does a horizontal line on a speed graph signify?

• The object is accelerating

• The object is moving backward
