Interpreting Motion Graphs

What is happening at D?

• Stationary
• Accelerating
• Fast steady speed; moving away from the starting position
• Slower steady speed; moving away from the starting position

What is happening at E?

• Stationary
• Accelerating
• Fast steady speed; moving away from the starting position
• Steady speed; returning to start position

What is happening at A?

• Stationary
• Accelerating
• Slower steady speed; moving away from the starting position
• Steady speed; returning to start position

Where is the object not moving

• A-B
• O-A
• C-D
• B-C

Which runner stopped for a rest?

• Albert
• Bob
• Charlie

What does this graph represent?

• Constant speed
• Acceleration
• Not moving

What is happening at C?

• Stationary

• Slower steady speed; moving away from the starting position

• The boat came to a stop after it traveled for 10 minutes. 
• The boat was at rest from 20 to 40 minutes. 
• The boat traveled the fastest in the last 20 minutes. 
• The boat traveled the shortest distance in the first 20 minutes. 

Which graph is showing positive acceleration (getting faster)

• D

• E

• both D and E

• neither D or E
