Semester 1

I have learned a lot about chemistry this summer. If I had to choose one activity that was my favorite I would have to pick the Air Rocket Lab. It was amazing that the rockets could go so high just using air pressure. I also like how Mr. Blake gives us time to ask questions if we do not understand something. Units 1-4 were really straight forward and I found them to be really easy. Units 5 and 6 are hard for me because sometimes I have trouble making the diagrams and I also feel that Unit 6 was kind of rushed. Overall this semester has been great and I am looking forward to another solid one.

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

Unit 4 - Projectiles
Axes are independent
Vegas rule- what happens on the x-axis stays to the x-axis and
what happens on the y-axis stays on the y-axis
T charts and put Unit 3 equations to use

Unit 5 - Forces in Equilibrium
SOH CAH TOA
Trig- Sin, cos, tan
Frictional Force (Ff)
Force = Push or pul
Force Diagrams, Normal force
Newton's Laws

Unit 6 - Forces in Motion
Fnet = mg (mass x gravity)
Friction = coefficient of friction (weird M) x Normal Force
