‭Study Guide Speed, Kinetic, and Potential energy‬ ‭Answer all of the following questions completely. There may be 2 or more parts to a‬ ‭question. Please answer each one fully for full credit.‬ ‭/24‬ ‭1. What is the definition of speed?‬ ‭2. Please find the speed of the following objects:‬ ‭‬ ‭A car traveled 30 miles in 30 minutes‬ ‭ peed:‬ S ‭‬ ‭A cheetah ran 450 meters in 14 seconds‬ ‭Speed:‬ ‭‬ ‭A rabbit ran 100 meters in 12 seconds‬ ‭Speed:‬ ‭‬ ‭A human ran 1 mile in.1 hrs‬ ‭Speed:‬ ‭‬ ‭A marble rolled 100 cm in 1.13 seconds‬ ‭Speed:‬ ‭. What 5 features of a typical car make it more safe to drive or possibly more safe in a‬ 3 ‭crash?‬‭Provide a brief explanation for each of how it improves safety‬‭.‬ ‭1.‬ ‭2.‬ ‭3.‬ ‭4.‬ ‭5.‬ ‭. During the speed lab you found the average speed for 3 trials. What mathematical‬ 4 ‭process did you use to do this?‬ ‭5. Find the average speed for a marble that traveled 200 cm in:‬ ‭ rial 1 - 1.5 seconds‬ T ‭Trial 2 - 2.1 seconds‬ ‭Trial 3 - 1.8 seconds‬ ‭Trial 4 - 1.9 seconds‬ ‭6. Identify the following speed graphs:‬ ‭‬ ‭A person drove at a constant speed, then got caught in slow moving traffic:‬ ‭________‬ ‭‬ ‭A person drove a little ways toward work, but got stopped at a stoplight.‬ ‭Thinking they forgot their phone, they turned around, but found it and‬ ‭proceeded on their way to work: _________‬ ‭‬ ‭A person immediately got caught in traffic, then the traffic ended and they‬ ‭were able to speed up. ________‬ ‭‬ ‭A person started driving toward work, but felt sick so they stopped for a few‬ ‭minutes. They decided to call in sick and returned home: ________‬ ‭Graph A‬ ‭Graph B‬ ‭Graph C‬ ‭Graph D‬ ‭. Create a motion graph to show the following trip: Gavin drove the first 3 miles toward‬ 7 ‭work in 6 minutes before realizing he drove past the building he works at! He sat at a‬ ‭stoplight for 2 minutes, then made a U-turn. It took him 4 minutes to drive the 1 mile‬ ‭back toward work.‬ ‭8. Using complete sentences, describe how potential and kinetic energy are related.‬ ‭. In the following picture, label the different phases of the roller coaster’s energy using‬ 9 ‭the terms listed below.‬ ‭‬ ‭Greatest Kinetic Energy, Least Potential Energy‬ ‭‬ ‭Equal Kinetic and Potential Energy‬ ‭‬ ‭Least Kinetic Energy, Greatest Potential energy‬ ‭10. What are the six types of potential energy?‬ ‭ ype: _________________________‬ T ‭Type: _________________________‬ ‭Type: _________________________‬ ‭Type: _________________________‬ ‭Type: _________________________‬ ‭Type: _________________________‬ ‭11. Choose 2 of the above types of potential energy and give an example of each.‬ ‭ ype: _________________________‬ T ‭ xample: __________________________‬ E ‭Type: _________________________‬ ‭Example: __________________________‬ ‭12. What are the 5 types of kinetic energy?‬ ‭ ype: _________________________‬ T ‭Type: _________________________‬ ‭Type: _________________________‬ ‭Type: _________________________‬ ‭Type: _________________________‬ ‭13. Choose 2 of the above types of kinetic energy and give an example for each.‬ ‭ ype: _________________________‬ T ‭ xample: __________________________‬ E ‭Type: _________________________‬ ‭Example: __________________________‬ ‭14. Identify the types of potential and kinetic energy in this example:‬ ‭ cross country runner eats a good breakfast and lunch, knowing they will have a long‬ A ‭run later that day. After school, the runner navigates 5 miles of trails, including one long‬ ‭1-mile climb that was very difficult. The downhill afterward was much easier.‬
