100
The study of Motion, Forces & Energy.
What is Mechanics?
100
The equation for speed.
What is Distance Traveled/ time traveled?
100
How quickly an object moves and in what direction the object is moving.
What is velocity?
100
Valid acceleration units (at least 2)
What is feet/second2, miles/hour2, meters/second2 etc
100
The motion of an object when it is falling solely under the influence of gravity.
What is free fall?
200
The first thing you need to know if you want to study the motion of an object.
What is position?
200
How quickly motion occurs.
What is speed?
200
A physical measurement that contains directional information.
What is vector quantity?
200
The time rate of change of an objects velocity.
What is acceleration?
200
The acceleration due to gravity for any object in English units.
What is 32 feet/ second2
300
A point against which position is measured.
What is reference point?
300
When communicating physical quantities this must always be included.
What is proper units?
300
How you calculate relative speed when objects travel in different directions.
What is by figuring the sum of their individual speeds?
300
The equation for calculating acceleration.
What is final velocity - initial velocity / time?
300
The science that describes how all things move.
What is physics?
400
The most import concept in physics.
What is all motion is relative?
400
A physical measurement that does not contain directional information.
What is scalar quantity?
400
If an object is slowing down then its acceleration is in what direction.
What is in the opposite direction as its velocity.
400
The acceleration due to gravity for any object in Metric units.
What is 9.8 meters/ second2
400
Without this information an answer to an accelerations problem is incomplete.
What is direction of acceleration?
500
Thomas Aquinas says that the presence of motion is an argument for the existence of God because motion cannot occur without this.
What is a mover?
500
How you calculate relative speed when objects travel in the same direction.
What is by figuring the difference between their individual speeds?
500
If an object is speeding up then its acceleration is in what direction.
What is in the same direction as its velocity.
500
The math calculation necessary to make sure you have the same units either of time or distance in an equation.
What is conversion?
500
Because of this, it is important to average data in a scientific experiment
What is experimental error?
