MECHANICS
The study of Motion, Forces & Energy.
What is Mechanics?
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?
Valid acceleration units (at least 2)
What is feet/second2, miles/hour2, meters/second2 etc
The motion of an object when it is falling solely under the influence of gravity.
What is free fall?
The first thing you need to know if you want to study the motion of an object.
What is position?
How quickly motion occurs.
What is speed?
A physical measurement that contains directional information.
What is vector quantity?
The time rate of change of an object's velocity.
What is acceleration?
The acceleration due to gravity for any object in English units.
What is 32 feet/ second2
A point against which position is measured.
What is reference point?
When communicating physical quantities this must always be included.
What is proper units?
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?
The science that describes how all things move.
What is physics?
The most import concept in physics.
What is all motion is relative?
A physical measurement that does not contain directional information.
What is scalar quantity?
If an object is slowing down then its acceleration is in what direction.
What is in the opposite direction as its velocity.
The acceleration due to gravity for any object in Metric units.
What is 9.8 meters/ second2
Without this information an answer to an accelerations problem is incomplete.
What is direction of acceleration?
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?
How 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 speeding up then its acceleration is in what direction.
What is in the same direction as its velocity.
The math calculation necessary to make sure you have the same units either of time or distance in an equation.
What is conversion?
Because of this, it is important to average data in a scientific experiment
What is experimental error?
