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