Tape Charts and Motion Graphs

What is a ticker tape diagram?

• A line of dots drawn on a page.

• A line of dots created by pulling ticker tape through a device that makes impressions on the tape at regular intervals. It represents the motion of the object that pulled the tape.

• A line of dots created by pulling ticker tape through a device that makes impressions on the tape at regular intervals. The dots are random and cannot be analyzed.

• A line of dots created by a machine that puts dots on tape at positions of your choice.

• A diagram of a piece of ticker tape.

What does it tell you if the dots on a piece of ticker tape are close together?

• The object was moving (relatively) slowly.

• The object was moving (relatively) fast.

• The object was speeding up.

• The object was slowing down.

• The object wasn't moving at all.

Which of the following pieces of ticker tape represent an object that is speeding up? (Assuming the ticker tape was pulled to the LEFT, through the device.)

• 
• 
• 
• 
• 

What does the solid line on this graph represent?

• Constant speed

• Acceleration

• At rest

• deceleration

This is a velocity-time graph.  What is the object doing in segment C?

• Positive acceleration
• Negative acceleration
• Constant Velocity
• Not moving

Calculate the mean velocity of the trolley for Strip A

• 0.2 cm/s

• 2 cm/s

• 20 cm/s

• 0.005 cm/s

What is the line on this graph showing?

• moving away from starting point at a constant speed

• moving back towards the starting point at a constant speed

• acceleration (getting faster)

• deceleration (getting slower)

Calculate the time that it took for Strip A to form

• 0.01s

• 0.1s

• 0.2

• 0.12

This graph demonstrates an object that is -

• Increasing speed
• At a constant speed
• Decreasing speed
• Stationary
