Define SOHCAHTOA |
Pneumonic used to know the three triginomic functions. Sin= Opp/Hypo Cos= Adj/Hypo Tan= Oppo/Adj |
Sound it out. What could it be used for. |
|
|
What is the "Hypotenuse" |
The longest side of a right triangle. Who's square is equal to the sum of the squares of the other angles (a^2 + b^2 = C^2) Whereas C is the length of the hypotenuse. |
Its long. |
|
|
What is the "Adjacent Angle or Side" |
The side that is next to (thus adjascent) to the angle in question; that is not the hypotenuse |
Whats next to the Hypotenuse? |
|
|
What is the "Opposite Side or Angle"? |
The side of angle that is directly opposite to the angle in question (specifically the vertex). |
Opposite to what? |
|
|
What is a "Sine or Sin" Function |
A function in Trig. Showing the ratio between the Opposite side and Hypotenuse in a right triangle for a given angle. The formula is Sin= Opposite/Hypotenuse |
Remember SOHCAHTOA |
|
|
What is a "Cos or Cosine" Function? |
A function in Trig. That shows the relationship ratio between the adjacent angle and hypotenuse for a given right triangle. The formula is Cos= Adjacent/Hypotenuse |
Remember SOHCAHTOA |
|
|
What is a "Tan or Tangent" Function? |
A function in Trig. Which shows the ratio or relationship between the Opposite and Adjacent Angles of a given right triangle. The formula is Tan= Opposite/Adjacent |
Remember SOHCAHTOA |
|
|
What is a Vector? |
A relationship of motion which has magnitude, size and DIRECTION |
|
|
|
What is a Scalar |
A relationship of motion that has magnitude and size |
|
|
|
What is the difference between a Vector and a Scalar? |
Whilst both are relationships of motion, Vectors show DIRECTION, magnitude and size whereas Scalars only show magnitude and size |
|
|
|
Define Displacement |
When referring to a vector, the distance traveled by a mentioned object in a given direction. The formula is S= V x T |
|
|
|
What is Velocity |
In Physics; the ratio of the distance an object traveled and the direction it is travelling in, divided by the time it took to reach that distance. The formula is V= Displacement/Time. |
|
|
|
What is Speed? |
In Physics, the ratio of how fast an object is moving in an unspecified direction. The formula is S= Distance/Time |
|
|
|
What is Distance? |
In Physics, the space or amount of area an object has traveled in an unspecified direction. |
|
|
|
What is the distance formula? |
Rate x Time |
|
|
|
In Physics, what is the annotation for displacement? |
S (or S with an arrow over it showing motion) |
|
|
|
What is the formula for Velocity? |
V= S(displacement)/Time |
|
|
|
What is the formula for displacement |
S= V(Velocity) X Time |
|
|
|
What is instantaneous speed? |
The speed of an object at a particular moment in time. |
|
|
|
What is Instantaneous Velocity? |
The rate of movement of an object in a given direction at a particular time. |
|
|
|
What is the formula for Average Velocity? |
V(avg)= Displacement(Change in X)/ Time (Change in Time) |
|
|
|
What is the difference when calculating Average Speed and Average Velocity? |
Average speed is just the total distance divided by the total time. Whereas Average veloctiy is the change in distance (displacement) divided by the total time. |
|
|
|
What is the formula for Acceleration? |
Change in Velocity / Time |
|
