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 rate of change of an object's velocity
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.
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 1 hour 45 mins.
Calculate his speed.
What is 16 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/ second2
In order for motion to occur
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 80-mile trip in 30 minutes?
What is 40 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/ second2
Why must 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?
