Definitions
A point against which position is measured
What is a Reference Point?
The equation for speed
What is distance traveled/time traveled?
How quickly an object moves and in what direction the object is moving
What is velocity?
Name at least two valid acceleration units
What is feet/second2
miles/hour2
meters/second2
The science that describes how all things move.
What is Physics?
A physical measurement that contains directional information.
What is Vector quantity?
How quickly motion occurs.
What is speed?
How you calculate relative speed when objects travel in different directions.
What is by figuring the sum of their individual speeds?
The equation for calculating acceleration.
What is final velocity - initial velocity/ time?
Without this information an answer to an accelerations problem is incomplete
What is direction of acceleration?
The time the rate of change of an object's velocity occurs.
What is Acceleration?
How do you calculate relative speed when objects travel in the same direction.
What is by figuring the difference between their individual speeds?
If an object is slowing down then its acceleration is in what direction
What is the opposite direction as its velocity?
The acceleration of an object that moves with constant velocity is zero. (True or False)
What is true?
Because of this, it is important to average data in a scientific experiment
What is experimental error?
The motion of the object when it is falling solely under the influence of gravity.
What is Free Fall?
A windsurfer traveled
28 km in 2 hours.
Calculate his speed.
What is 14 kph?
If an object is speeding up then its acceleration is in what direction
What is the same direction as its velocity?
The acceleration due to gravity for any object in English units.
What is 32 feet/ second^2?
In order for motion to occur, this must happen.
What is an object's position must change?
A physical measurement that does NOT contain directional information
What is Scalar quantity?
How many miles per hour does a car travel if it makes an 30-mile trip in 30 minutes?
What is 60 mph?
The math calculation necessary to make sure you have the same units either of time or distance in an equation.
What is conversion?
The acceleration due to gravity for any object in Metric units.
What is 9.8 meters/ second^2
This is the reason to one use a reference point to determine whether or not an object is in motion.
What is "It allows you to determine whether or not position changes"?
