Definitions
A point against which motion is measured
What is Reference Point
The distance an object travels during a certain amount of time is...
What is speed
True or false: Acceleration is a vector quantity
True
Distance/time=?
What is Speed
When graphing this is indicated by a dashed line, it is used to estimate values that are either higher or lower than the actual data collected
What is extrapolation
Using a reference point to detect motion
What is Frame of Reference
The ratio of the total distance traveled to the total time of the trip
What is Average Speed
Module 6 is all about what kind of science
What is Physics
What is this equation for
(final velocity-initial velocity)/time
What is acceleration
The steepness of a graph line
What is slope
The distance an object travels plus the direction from the starting point
What is is Displacement
The change in an object's velocity over time
What is Acceleration
This helps scientist accurately report their calculated answers, it also involves a specific way scientist round their answers
What is significant figures
How is relative speed calculated when objects travel in the same direction?
By taking the difference of the two relative speeds.
(relative speed=speed of object 1-speed of object 2)
What does the slope of a distance-time graph represent?
What is speed
A physical measurement that contains both magnitude (number) and directional information
What is Vector Quantity
The rate at which an object is moving at a given moment in time
What is Instantaneous Speed
How tall was the pile of books in our experiment last week?
What is eight inches
How is relative speed calculated, when objects travel in opposite directions?
By adding their individual speeds
(relative speed=speed of object 1 + speed of object 2)
How is constant speed shown on a graph?
What is a straight line
A physical measurement that contains only magnitude (number) and does not contain directional information.
What is Scalar Quantity
This points directly from the starting point to the ending point
What is a resultant vector
This tells you how quickly and object moves in relation to a reference point
What is speed
When working with physical quantities in equations, you must keep the units with ?
What is the numbers
How is changing speed shown on a line graph?
What is a curved line
