Describing and Measuring Motion
Speed
Velocity
Earth's Motion
Acceleration
100
This is necessary to determine whether or not an object is in motion
What is a reference point?
100
This is the rate of distance an object travels per unit of time.
What is speed?
100
When you know the speed and direction of an object, you know this about the object.
What is the object's velocity?
100
This is the name of the landmass that once contained all of the Earth's continents.
What is Pangaea?
100
This is the rate at which velocity changes.
What is acceleration?
200
An object is in motion if it does this relative to a reference point.
What is changes position?
200
This is the formula used for calculating speed.
What is distance/time (distance over time)
200
In this career, knowing an object's velocity is important.
What is an air traffic controller? (accept other reasonable answer-teacher's discretion)
200
The pieces by which the earth's rocky outer layer is formed
What are plates?
200
True or false: A car speeding up is accelerating.
What is true?
300
This is the system of measurement used by the scientific community worldwide.
What is the Internationale System of Units (will also accept SI or Systeme Internationale)
300
This kind of speed, which is not constant, is calculated by dividing total distance traveled by total time.
What is average speed?
300
This is the reason why it is important to know a storm's velocity.
What is so you can know if the storm will have an impact on your area (accept other reasonable answer-teacher's discretion).
300
The concept by which scientists explain how landmasses have changed over time.
What is The Theory of Plate Tectonics?
300
True or false: a butterfly coming in to land on a flower is accelerating?
What is true?
400
This concept refers to the idea that you are in motion depending on which reference point you choose
What is relative motion?
400
This is the rate at which an object is moving at a given instant in time
What is instantaneous speed?
400
True or false. Velocity can be calculated without knowing the speed of an object.
What is false?
400
These take place in the mantle, causing the Earth's plates to move.
What are convection currents?
400
True or false: A person sleeping is accelerating.
What is false.
500
This is the number of millimeters there are in 14.5 meters.
What is 14,500 millimeters (mm)?
500
A cyclist traveling at an average speed of 45 km/3 hr is moving at this rate per hour.
What is 15 km/hour?
500
Stunt pilots use velocity for this reason.
What is to avoid collisions (accept reasonable answers-teacher discretion)
500
This describes the rate of motion of the Earth's plates.
What is slow or very slow (accept other reasonable answers-teacher's discretion)?
500
This is the formula for calculating acceleration.
What is final speed - initial speed/time (final speed minus initial speed over time).
