- Unit 5 - Part 2 Centripetal acceleration Assessment Centrifugal force is something that: ain't even real is super real is the same as centripetal force only exists when moving really fast
- Unit 5 - Part 2 Centripetal acceleration Assessment Objects moving in a circle have a centripetal force push them in which direction? up down toward the center of the circular path toward the outside of the circular path
- The following question has two parts. First, answer Part A. Then, answer Part B. Part A: A person pulls the rope in Pulley C by 3 meters and lifts the load by 1 meter. Using the equation for work, how much work is done by the person on the pulley and by the pulley on the load? The person does 600 of work on the pulley, and the pulley does 200J of work on the load. B The person does 200 of work on the pulley, and the pulley does 200J of work on the load C The person does 200 of work on the pulley, and the pulley does 600J of work on the load. D The person does 600 of work on the pulley, and the pulley does 600J of work on the load. Part B: Based on Part A, which statement BEST describes how a pulley affects the total amount of work done by the machine? A A pulley decreases the amount of work done by the person and by the machine. B A pulley does not affect the total work that must be done by the person or the machine. A pulley decreases the amount of work done by the person and increases the amount of work done by the machine. D A pulley increases the amount of work done by the person and decreases the amount of work done by the machine.
- Unit 5 - Part 2 Centripetal acceleration Assessment Objects moving in a circle are always accelerating because they are always changing their: spoed ) time distance direction
