  1. Motion Study Guide & Notes Mr. Rosato’s Honors Physical Science Fall 2013

  2. Slope of a Curve Slope shows how much y changes with x Y Y Slope = 3/2 X X

  3. Slope of a Distance-Time (DT) Curve

  4. Slope of a Distance vs. Time Graph (DT) is SPEED! Slope

  5. Slope of a Speed/Velocity-Time (VT) Graph is ACCELERATION!

  6. Reading a Velocity-Time (VT) Graph • The slope of a VT graph shows how fast the speed is changing – or how the object is accelerating

  7. Acceleration

  8. Calculating Acceleration

  9. A rocket can move 100 kilometers in 4 seconds. What speed is it moving at? • What speed (in m/s) is a skateboarder moving if he can skate 10 kilometers in 10 minutes? • A red Ferrari zooms over 500 metres in 4 seconds. What is its speed? • How long would it take a snail to slither 20 meters at 5 meters per hour? • How many seconds does it take an Indy race car to travel a 240 meter straight section at 80 m/s?

  10. 1. How fast is a bird flying if it goes 50 meters in 5 seconds ?  2. If a lizard crawls 10 meters in 20 seconds, what is its speed? 3. If a fish swims a distance of 4 km in 2 hours, what is its speed?  4. If a baseball is traveling at 60 m/s, how far will it go in 3 seconds? 5. How much time will it take a bike going 5 m/s to travel 20 meters ? 6. If a sprinter runs 40 meters in 5 seconds what is his speed? 7. If an insect travels for 300 seconds at a speed of 2 cm/second, how far will it have traveled?

  11. Acceleration Questions • A car accelerates from 20 m/s to 40 m/s in 5 seconds. What is its acceleration? • A motorbike speeds up from a standing start (that is, 0 m/s) to 30 m/s in 4 seconds. How fast is its acceleration? • When she sees the red traffic light, Marie brakes to a halt from a speed of 70 meters per second in just 2 seconds. What is her deceleration (negative acceleration? • A skydiver falling from an aircraft falls at 9.8 m/s2. What is his speed after 3 seconds? 18. • Toon Train is traveling at the speed of 10 m/s at the top of a hill. Five seconds later it reaches the bottom of the hill and is moving at 30 m/s. What is the rate of acceleration of Toon Train? • Pete the Penguin loves to sled down his favorite hill. If he hits a speed of 50 m/s after 5 seconds, what is his rate of acceleration? Hint: He starts at 0 m/s at the top of the hill. • Monster Mike’s truck decelerates from 72 m/s to 0 m/s in 6 seconds. What is his rate of deceleration?
