What is Momentum?
What is the formula? |
A vector quantity equal to the product of the mass and the velocity of an object
|
P -> = MV->
|
|
|
What is Impulse?
What is the Formulae? |
The product of Force and Time
|
F-> net change in T = M net change in V ->
|
|
|
What are the units for Impulse?
What are the units for Changes in Momentum? |
Impulse is N. s
Change in Momentum is Kg.m / s |
|
|
|
What is Force?
|
Any influence that causes an object to under go change.
|
|
|
|
What is Quantative Analysis?
|
Mathmatical description
|
|
|
|
What is the difference between Mass and Weight?
Mass and Volume? |
Mass is how much matter is in an object... weight is the effect gravity has on that object.
Mass is how much matter versus Volume which is how much space is it occupying. |
|
|
|
Compare "Change in Momentum" with "Net Force"
With Acceleration? |
They are the same... why?
|
|
|
|
What is Power?
|
Power is the value you get when you divide the work done by the time it takes to do the work.
|
|
|
|
What does SI mean?
|
International Standards used for Scientific Notation
|
|
|
|
What's the difference between kg.s and kg/s
|
Both mean the same but conventionally . comes before / when two ratios are being expressed in the same statement.
|
|
|
|
What is "Conservation of Momentum in an Isolated System"?
|
A theoretical law of physics that assumes an "isolated system is possible" and that any momentum within that system is fully retained regardless of interactions of objects and forces within that system.
|
|
|
|
What is "Conservation of Linear Momentum"?
|
Net momentum is conserved as a Vector Quantity during any interaction between two or more objects.
|
|
|
|
What is a Vector Quantity?
|
Anything that has Magnitude and direction.
|
|
|
|
What is Magnitude?
|
Size
|
|
|
|
What is the difference between Momentum versus Power
|
Power is the rate at which energy is converted to produce work
Momentum is the product of mass and velocity. |
|
|
|
What is the formulae for calculating the circumferance of a circle?
|
C = 2 pi r
|
|
|
|
What is the formulae for calculating the area of a triangle?
|
Area = 1/2 Base X Height
|
|
|
|
Reduce the expression
A = 1/2 x 6 x 19 |
A = 1 x 3 x 19
|
|
|
|
How do you calculate the area of a trapezoid?
|
A = 1/2 h (b1 + b2)
The area of a trapezoid is equal to 1/2 of the height times the sum of the two bases. |
|
|
|
How do you calculate the volume of a cone?
Explain why this formulae works? |
1/3 pi R squared x H
|
|
|
|
How do you calculate the surface area of a cone?
|
The area of a cone is equal to the area of it's base added to the area of it's surface.
|
|
|
|
What is the median of the following:
3, 211, 67, 52 |
First arrange them in ascending order:
3, 52, 67, 211 Then take the middle number or average the adjacent numbers |
|
|
|
Distinguish between mean, median and mode
|
Mean = average (arithmetic)
Median = middle Mode = frequency |
|
|
|
What are the rules for evaluating a mathmatical expression?
|
Reduce, multiply, add and subtract and then divide.
|
|
|
|
How much is three times the amount you get when you subtract six from the four fifths of the exponential value of negative three?
|
-3 exponentially by 4/5 minus 6 times three.
|
|
|
|
What is the distributive property of -4x+3y (14-xy)?
|
The coefficient -4x+3y is the distrributive property meaning it has to be applied equally to all values within the brackets.
|
|
|
|
What is the midpoint formulae?
|
A formulae for finding the middle of a line segment:
(x1 + x2)/2, (y1 +y2)/2 |
|
|
|
What is the formulae for finding the distance between two points on a graph?
Why does this formulae work? |
Take the square of the difference between the two x values of each point and add them to the values of the differences between the two y points. Then take the square root of that value.
|
|
|
|
What is a polynomial
|
One or more summed terms consisting of a constant and a variable raised to integral values
|
|
|
|
What is a term
|
An expression of product or quotient
|
|
|
|
Use FOIL to reorder
(y+4)(-6y+3) |
First Outer Inner Last
|
|
|
|
Distinguish between "factor", "Simplify", "Solve", and "Evaluate"
|
Provide examples of each
|
