Unit 1: Measurement
This is the acronym we learned to remember how to convert units in the metric system.
What is King Henry Died Unexpectedly Drinking Chocolate Milk?
This is the unit velocity is measured in.
What is meters per second?
This is the acceleration due to gravity on Earth.
What is 9.8 m/s/s?
This is what a horizontal line looks like.
What is ----------------------?
This is the number of students in the 9th grade class. (plus or minus 3)
What is 107? (will accept 104-110)
This is how many centimeters are in a meter.
What is 100?
A vector, such as velocity, contains both magnitude and _______________________.
What is direction?
Acceleration is a change in _________________________ over _______________________.
What is velocity ; time ?
True or False: A horizontally launched object’s vertical velocity changes throughout its trajectory.
What is true?
This is the only "fictitious force" we have talked about in this course.
What is centrifugal force?
4.6 L = ____________________ mL
What is 4600?
This is the equation for distance if you are given speed and time.
What is speed x time?
This is what the slope of a velocity vs. time graph tells you.
What is the acceleration?
True or false: Neglecting air resistance, the mass of a horizontally projected object affects how long it takes to fall.
What is false?
This is the name of the next unit we will learn after break.
What is energy, work, and power?
If a car drives 6 kilometers to the right, then stops for 1 hour, and then drives 2 kilometers back to the left, this is their displacement (distance and direction) in meters.
What is 4000 meters to the right?
This is how you show acceleration on a distance-time graph.
What is a curved line?
On a velocity vs. time graph, this is what it means if something is below the x-axis.
What is it is going backwards?
The only factor that affects the time it takes a horizontally launched projectile to hit the ground is the ________________ from which it was projected.
What is height?
This is the name of either one of Ms. Murphy's dogs.
What is Moose or Margot?
A track runner runs exactly 5 laps around a 400 meter track. This is their distance and displacement.
What is 2000 m distance and 0 m displacement?
A car is traveling at a constant rate of 85 miles per hour. This is how far can it go in 5 hours.
What is 425 miles?
A bicycle rider decreases her speed from 15 m/s to 5 m/s in 5 seconds. This is her acceleration.
What is -2m/s/s.
Neglecting air resistance, this is how fast a free falling object would be going vertically after 3 seconds.
What is 29.4 m/s?
This is the year Isaac Newton was born. (plus or minus 5 years)
