,Uncertainty:
1.2: Uncertainties and Errors
- Where unit is in the measurement tell us if the value is fractional or absolute
- Round absolute uncertainty to 1 sig fig
Propagating Uncertainty:
Addition and Subtraction
Multiplying and Dividing
,Roots and Powers
- Power or 1/m MULTIPLIED by fractional uncertainty
Mechanics:
2.1: Motion
Graphs Describing Motion:
, Equations of motion for uniform acceleration:
*if acceleration is constant, the following equations can be used
V = final velocity
U = initial velocity
A = acceleration
S = displacement
T = time
Projectile Motion:
Free fall:
−2
Symbol: g Value: 9.81𝑚𝑠
*If only the force acting on a object is the force of gravity, the
object is in free fall
Rules:
−2
1. Acceleration is alway g and always points down -acceleration is 9.81𝑚𝑠 in the
y-component/ vertical direction
−1
2. If the initial velocity = 0𝑚𝑠 the object is in free fall
3. If the object is thrown upwards, its velocity at the highest point = 0
X-direction = the velocity remains the same
Y-direction the velocity changes by 9.81 - add velocities tip to tail method
Rules for 2-D Projectile motion: Movement in both horizontal and vertical direction
1. X-direction acceleration is always 0
2. You can only use kinematic equations for one direction at a time
3. Time is the only variable that changes between x and y components
Wording:
“Launched off” or “falls of flat surface” = NO initial velocity u = 0
‘Highest point in motion” or “Max height reached’ - y-velocity = 0
“Range” = total x displacement
