A long tape is attached to a moving trolley and threaded through a device that places a tick upon the tape at regular intervals of time.

The movement of a trolley down a slope was investigated using ticker tape with a frequency of 50 Hz. The ticker tape produced 50 dots per second.

The 14 cm length of the ticker tape was cut into four strips. It was cut through the middle of the first and then the sixth hole.

What is meant by acceleration?

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.
