Motion Study Guide & Notes Mr. Rosato’s Honors Physical Science Fall 2013
Slope of a Curve Slope shows how much y changes with x Y Y Slope = 3/2 X X
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
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?
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?
