Quarter 1 Review

During the first quarter we learned a ton of physics. We learned about moving objects and how to determine how fast they are going. Here is a summary of what we have learned so far throughout the first three units.

Unit 1 -  Introduction to Physics
Pendulum Lab
Graphing relationships and functions, no relationship y=b, liner/direct y=x, inverse y=1/x, squared y= x^2, square root y=√x
Independent and Dependent variables, x = independent,  y = dependent (in most cases)
Scientific Notation, 525,000 = 5.25 x 10^5
Accuracy vs. Precision, accuracy = closeness, precision = consistency
Units of Measurements,
Dimensional Analysis (converting) 6.4 hrs = 23,040 secs

Unit 2 - Kinematics: The Study of Motion
Describing graphs, Motion maps,
Velocity, V(m/s) = D/T
Displacement, distance
Instantaneous speed,
Physics Olympics,
Kinematics,
Position vs. Time, slope = velocity (graphing rule #1)
Velocity vs. Time, slope = acceleration (graphing rule #2)
The area under the curve of a VT graph is displacement (graphing rule #3)

Unit 3 - Uniform Acceleration
Instantaneous velocity,
Average Velocity,
Constant acceleration,
Gravity = 9.8 m/s^2 ≈ 10 m/s^2
DAT, d = 1/2 at^2 + vot
VAT, v = vo + at
VAD, v^2 = vo^2 + 2 ad
