Scientific Method
An educated guess, contains a "if... then..." statement.
What is a Hypothesis?
a2+b2=c2
What is Pythagorean's Theorem?
A quantity that has both magnitude and direction
What is a Vector?
9.81 m/s2
What is gravity? or What is g?(Numerical value)
A parabola
What is the trajectory of a projectile?
A chart that displays information as a series of data points over time that can be connected.
What is a line graph?
A mnemonic device that helps us to remember trigonometric functions.
What is SOH CAH TOA?
The change in displacement/distance over time.
What is speed/velocity?
The movement of an object or body only under the influence of gravity
What is Free Fall?
45 degrees
What is the angle that gives the maximum range of a projectile?
Factors in your experiment that remain constant and unchanged.
What are controlled variables?
y = mx + b
What is the Slope Intercept Form Equation?
The change in velocity of an object over time.
What is acceleration?
The variable that denotes vertical displacement, or height.
What is ∆y?
Horizontal & Vertical
What are the components/directions of Projectile Motion?
Factors in your experiment that you change.
What is the independent variable?
A system of a measurement that is based on the meter.
What is the metric system?
The variable that denotes total change in position.
What is ∆x?
The force acting on an object that is moving through air flowing in the opposite direction.
What is Air Resistance? or What is Drag?
The horizontal distance that a projectile covers.
What is Range?
Factors in your experiment that responds to changes.
What is the dependent variable?
A process for unit elimination that alleviates confusion through scribal strokes and oral sounds.
What is the Pereyra Method?
Speed, Distance, Time, Temperature
What are scalar quantities?
The constant speed that a freely falling object eventually reaches when the resistance of the medium (air, water) through which it is falling, prevents further acceleration.
What is Terminal Velocity?
The highest vertical displacement of a projectile.
What is the Apex? or What is Altitude?
Will NOT accept HEIGHT or HIGHEST POINT.
