Presentation Transcript

  1. Review Trashketball • What is the formula for speed? • S = d/t • What is the formula for velocity? • V = displacement/time • What is instantaneous speed? • Speed the does not vary • What is the different between distance and displacement? • Distance= total amount traveled • Shortest distance/difference between where the object started and where is ended

  2. Review Trashketball • What is the difference between positive and negative acceleration? • Positive = speeding up Negative= slowing down • Acceleration is change in speed and what else? • Change in direction • How would you show no motion in a distance vs time graph?

  3. Trashketball Review • What is needed to determine velocity? • Distance, time, and direction • What is the definition of motion? • When an object changes position • Anna ran 100 meters in 20 seconds. What was her average speed? (don’t forget your units) • 5 m/s • Superman flies at 500km/hr. How far will he go in 3 hours? • 1500 km • How long will it take a train going 120km/hr to travel 540km? • 4.5 hours

  4. Trashketball • A. 5m = _____ cm B. 75cm = _______ mm C. 121km= _____m • A. 500 cm B. 750 mm C. 121,000 • A. 17,000m = __km B. 48,000 mm = _____m C. 5,000mL = ____L • A. 17 km B. 48 m C. 5L • 427 L = ____ mL B. 43,000 mg = ______ g C. 27.6g = ____mg • A. 427,000mL B. 43g C 27,600
