,Chapter 1 - ANSWER✅Physical Quantities and Vectors
What are the three fundamental physical quantities? - ANSWER✅Mass (kg), length
(m), time (s)
Multiplication and Division (Significant Figures) - ANSWER✅Result can have no more
significant figures than the factor with the fewest
Addition and Subtraction (Significant Figures) - ANSWER✅Determined by the term
with the fewest digits to the right of the decimal point
Scalar Quantity - ANSWER✅Numbers, combine according to usual rules of arithmetic
Vector Quantity - ANSWER✅Have direction and magnitude, combine with vector
addition
The negative of a vector has the same.... but..... - ANSWER✅Same magnitude but
points in the opposite direction
Vector addition - ANSWER✅Rx = Ax + Bx + Cx
Ry = Ay + By + Cy
(y-component vs x-component)
How to find magnitude of total vector? - ANSWER✅A = √(Ax² + Ay² + Az²)
Unit vector - ANSWER✅Describe direction in space
→A = Axi + Ayj + Azk
→B = Bxi + Byj + Bzk
→R = (Ax+Bx)I + (Ay+By)j + (Az+Bz)k
How to find direction? - ANSWER✅∅ = tan⁻¹ (Ay/Ax)
Dot Product - ANSWER✅C = →A . →B is a scalar quantity
C = ABcos∅ = |A|*|B|cos∅
OR
C = AxBx + AyBy + AzBz
Dot product of two perpendicular vectors? - ANSWER✅Zero
Vector Product - ANSWER✅→C = →A x →B is a vector quantity
C = ABsin∅
Cx = AyBz - AzBy
, Cy = AzBx - AxBz
Cz = AxBy - AyBx
Where does the direction of a cross-product go? - ANSWER✅Perpendicular to the
plane of the two vectors being multiplied (right hand rule)
Cross product of two parallel or antiparallel vectors? - ANSWER✅Zero
Chapter Two - ANSWER✅Motion Along a Straight Line
A particle's average x-velocity during a time interval - ANSWER✅v av = x2-x1/t2-t1
A particle's instantaneous x-velocity at any time - ANSWER✅lim ∆t→0 dx/dt
Velocity is the time derivative of the position function
Average x-acceleration - ANSWER✅v2x - v1x/t2 - t1
Instantaneous x-acceleration - ANSWER✅lim ∆t→0 dvx/dt
Acceleration is the time derivative of the velocity function
What can be used when x-acceleration is constant? - ANSWER✅Kinematics
Kinematic equations - ANSWER✅v = v₀ + at
x = x₀ + v₀t + ½at²
v² = v₀² + 2a(x-x₀)
x - x₀ = ½(v₀ + v)t
Which one should I use when time is not a factor? - ANSWER✅v² = v₀² + 2a(x-x₀)
Free fall - ANSWER✅A case of motion with constant acceleration which is due to g, or
9.81 m/s². This acceleration is always downward (-g)
Straight line motion with varying acceleration - ANSWER✅When acceleration is
changing function of time, find velocity and position by integrating the acceleration
function
v = v₀ + (integral from 0-t) a dt
x = x₀ + (integral from 0-t) v dt
x-t graph (Fig 2.8) - ANSWER✅If slope is positive, v > 0
If slope is negative, v < 0
If slope is zero, v = 0
Number line approach/motion diagram - ANSWER✅Small arrow = slower velocity
Large arrow = faster velocity
