100
This is the name of the equation used to solve for the Magnitude of the resultant vector
What is the Pythagorean Theorem
100
This is how long an object falls for when it is launched horizontally from a height of 5 meters. (g = -10 m/s2) (Use the Free Fall Distance/Time Diagram)
What is 1 second
100
This is the Model of Motion that the horizontal axis (x) follows (Constant Velocity/Uniform Acceleration)
What is Constant Velocity
100
This is the method in which we determine the Range, Maximum Height, and Hang Time of a projectile
What is the Straight-Line Projectile Diagram
200
This is when I have a triangle that has sides that equal a factor of 3 and 4, and the hypotenuse equals a factor of 5
What is a 3, 4, 5 triangle
200
This is how far an object moves horizontally (x) when it is launched from a 5 meter high table at 2 m/s. (Use Free Fall Distance/Time Diagram for time)
Deltad_x=V_L*Deltat
What is a range of 2 meters from the table
200
This is the Model of Motion that the vertical axis (y) follows (Constant Velocity/Uniform Acceleration)
Uniform Acceleration
200
This is the model of motion in the horizontal (X) axis a projectile follows while it is rising up and falling back down.
What is Constant Velocity
300
This is the equation used to solve for the Magnitude of a Resultant Vector
What is
R = sqrt(X^2+Y^2)
300
This is the height an object is launched from if it has a Hang Time of 3 seconds
What is a height of 45 meters
300
This explains the time is takes for a dropped object and a horizontal projectile released from the same height to hit the ground
What is they both hit at the same time
300
This is the Hang Time of a projectile with a Horizontal Velocity of 5 m/s and a Vertical Velocity of 20 m/s
What is 4 seconds
400
This is the magnitude of a resultant when a Vector going 3 meters to the East adds a Vector going 4 meters to the North.
What is 5 meters
400
This is how fast an object is launched (VL) horizontally from a table if its Hang Time is 3 seconds and its range is 15 meters
V_L=(Deltad_x)/(Deltat)
What is 5 m/s
400
This is the only variable in a horizontal projectile problem that can be used on both the horizontal (x) and vertical (y) side of the table
What is time
400
This is the max height a projectile reaches when launched with a Horizontal Velocity of 5 m/s and a Vertical Velocity of 20 m/s
What is 20 meters
500
This is 500 meters East + 250 meters North
What is 559.0
500
This is how far an object travels when launched from a height of 80 meters and with a launch velocity (VL) of 10 m/s. (Use the Free Fall Distance/Time Diagram to solve for time or the equation below)
(Deltat)=sqrt((2*(Deltad_y))/g)
Deltad_x=V_x*(Deltat)
What is 40 meters
500
This is known as the optimum launch angle
What is 45*
500
This is the range a projectile travels when launched with a Horizontal Velocity of 5 m/s and a Vertical Velocity of 20 m/s
What is 20 meters
