TICKER TIMER

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 choice best describes the motion shown in the ticker tape diagram?

• Constant speed throughout

• speeding up, constant speed ,slowing down, constant speed

• slowing down, constant speed, speeding up, constant speed

• slowing down then speeding up

• the motion of the object is slower.

• the motion of the object is faster.

• the motion of the object does not change.
