Vocabulary One
Relative motion
5m South
vector
What are the standard, international units for length?
meter, m
What is the speed of an object traveling for 10s for a total distance of 20m?
Make sure to include your units!
2m/s
What is the speed of the object if it travels 110m in 10s?
Hint: Speed = distance/time
Make sure to include your units!
Speed = 110m/10s
speed=11m/s
A quantity with magnitude and direction
Vector
10 meters/second
scalar
What are the standard, international units for time?
seconds, s
What is the speed of an object traveling for 200m over 50s?
Make sure to include your units!
4m/s
The world record holder for fast car speed is the ThrustSCC, a jet propelled car, at 341m/s. At just 10 seconds, how far would the car have traveled?
Hint: distance=speed x time
Make sure to include your units!
3410 meters
341 meters per second x 10 seconds
FYI: 3410 meters is approximately 2 miles, or 1 mile every 5 seconds!
A quantity with magnitude (size) only, no direction.
Scalar
What are the standard, international units for displacement?
meters/second (m/s)
What are the standard, international units for distance?
meters, m
How far has an object traveled if it is going 2m/s over a period of 500s?
Make sure to include your units!
Hint: speed x time = distance
1000m
A bluebird spots a worm in the dirt 120,000m away. It travels at a rate of 20m/s trying to reach the worm before the yellow bird. If the yellow bird takes 8 seconds to reach the worm, which bird reached the worm the fastest?
Make sure to include your units!
Hint: time=distance/speed
The bluebird reached the worm in 6 seconds.
120000 seconds /20 meters per second
The ddistance an object travels over time.
Is this a scalar or vector?
Speed, scalar
How is distance different than displacement?
Distance has no direction, but displacement does.
What are the standard, international units for velocity?
meters/ second (m/s)
How far has an object traveled if it takes 325s to get to its destination going at 10m/s?
Make sure to include your units!
Hint: speed x time = distance
3,250m
How long did it take a hot air balloon to reach an altitude of 5000m as it traveled 5m/s?
Make sure to include your units!
Hint: Time = distance/speed
1000s
The cange in position of an object.
Is this a scalar or vector?
Displacement, vector
What is the displacement of an athlete that runs around a circular track at 4m/s, starting and ending at the 0m mark? They travel east, north, west and then south back to east.
What are the standard, international units for acceleration?
meters/ second squared (m/s2)
It takes Gina 5000s traveling at a speed of 5m/s to get to her destination. How far away is her destination?
Make sure to include your units!
Hint: speed x time = distance
25000m
How long did it take a train rolling along at 25m/s over a distance of 250m to get to a stop at the end of its journey?
Hint: time=distance/speed
Make sure to include your units!
250 meters per second/ 25 meters= 6s
