This educational resource from C. Towle at MTAScience.com helps students differentiate between instantaneous and average velocity. By analyzing four specific scenarios, learners identify whether the velocity described is instantaneous or average. The examples provided include a car's speedometer reading, a race car driver's consistent speed, the speed of a freely falling object, and a posted speed limit. This exercise enhances the understanding of velocity concepts in physics and encourages students to apply their knowledge to real-life situations.

Science Starters Instantaneous or Average Velocity C. Towle at www.mtascience.com for T. Trimpe 2009 http://sciencespot.net/
For each use of velocity described below, identify whether it is instantaneous velocity or average velocity. 1. The speedometer on your car indicated you are going 65 mph. 2. A race-car driver was listed as driving 120 mph for the entire race. 3. A freely falling object has a speed of 19.5 m/s after 2 seconds of fall in a vacuum. 4. The speed limit sign says 45 mph.
The answers are … 1. instantaneous 2. average 3. instantaneous 4. Instantaneous
