Position, Distance, and Displacement
========================================================
Hello! Lets begin!
1. Which answer best describes displacement?
- A) Displacement is a vector quality showing total length of an area traveled by a particular object.
2. Kelley is playing pool and hits the cue into the nine ball, which is directly in the center of the pool table. The nine ball travels a total of 7 meters before stopping, 1 meter to the left of the initial starting point of the nine ball. Which sentence reflects the correct statement regarding distance and displacement when considering the motion of the nine ball?
- D) The nine ball traveled a distance of 7 meters and was displaced by 1 meter.
3. What is velocity?
- B) Velocity is a vector quantity that tells the distance an object has traveled over a period of time.
4. Imagine a time-position graph where the velocity of an object is constant. What will be observed on the graph concerning the slope of the line segment as well as the velocity of the object?
- C) The slope of the line is equal to zero and the object will be stationary.
5. Select the option that best summarizes the reason for the use of position-time graphs when studying physical science.
- B) The position-time graphs show the relationship between the position of an object (shown on the y-axis) and the time (shown on the x-axis) to show velocity.
