Kinematics II

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.

1. Which of the following statements about speed and velocity is correct?

• Velocity only describes an object’s rate of motion.

• Speed describes how an object is changing its velocity.

• Speed and velocity both describe how an object is speeding up.

• Only velocity includes the direction an object is traveling.
