If you walked 15 meters to the right and then 6 to the left what is your displacement if the origin is 0? 9 Meters
If you walked 6 to the right and 3 to the left what is the distance? 9 Meters
An object is moving for 10 seconds and went a total distance of 100 meters. What was the speed? 10 m/s
T/F If the velocity of an object is constant, its acceleration must be zero True
T/F An object can be moving for 10 seconds and still have zero displacement True
T/F A vector is a large quantity and a scalar is a small quantity False
T/F The quantity 20 m/s is a speed and such is a scalar quantity True
An object was traveling for 10 m/s and went a total of 20 meters. How long did it take them to reach the 20 meters? 2 seconds
Formula for velocity Xf - Xi --------- t
What do you round to when calculating velocity? Hundreths
An object starts 10 meters from the origin and ended up -3 meters from the origin. This took 13 seconds. What is the velocity? -1 m/s
