Understanding Speed Graphs and Motion

The video tutorial focuses on understanding motion graphs, specifically speed graphs. It explains the relationship between speed, distance, and time, highlighting how time is an independent variable while distance is dependent. The tutorial analyzes different graph lines, such as vertical, horizontal, and negative slopes, to interpret speed and motion. Interactive questions are posed to engage students in identifying graph characteristics, such as constant speed and acceleration. The video concludes with practice questions to reinforce graph interpretation and speed calculation skills.

What are the two main variables involved in calculating speed?

• Acceleration and Time

• Distance and Time

• Distance and Velocity

• Speed and Velocity

Why is time considered an independent variable in speed graphs?

• Because it depends on speed

• Because it is constant

• Because it can change

• Because it is measured in seconds

What does a steep and straight line on a speed graph indicate?

• Acceleration

• Fast and constant speed

• Variable speed

• Slow speed

How can you tell if an object is accelerating on a speed graph?

• The line is vertical

• The line is straight

• The line is curved

• The line is horizontal

What does a horizontal line on a speed graph signify?

• Deceleration

• Stationary object

• Acceleration

• Constant speed

What does a negative slope on a speed graph indicate?

• Object is accelerating

• Object is stationary

• Object is returning to start

• Object is moving at constant speed

Which graph shows the object traveling at the fastest speed?

• Graph C

• Graph B

• Graph A

• Graph D

Which part of the graph shows an object that is stationary?

• Part B

• Part A

• Part C

• Part D

Which line shows an object that is accelerating?

• Line A

• Line C

• Line D

• Line B

How long was the cyclist stationary for?

• 220 seconds

• 100 seconds

• 80 seconds

• 40 seconds
