What you need to know for the Unit 1 Test (Fri Sept 23 – B, Mon Sept 26 A)

Basic Trigonometry
Sin, Cos, Tan,  (we’ll hold off on arcSin, arcCos, and arcTan till later in the semester)
Pythagorus’ Theorem

The difference between vectors and scalars (velocity and speed)
Converting units
Powers of 10, scientific notation
Significant Figures

How to derive the General Equation of Kinematics and how to derive the ‘time independent’ equation of kinematics using the 2 column derivation method.

The derivations are in this power point

acceleration-part-2

How to solve 1 dimensional motion problems
How to solve gravitational acceleration (free fall) problems
How to solve girlfriend problems (extra credit)
How to solve time independent motion problems

# Acceleration (motion under constant acceleration) – Part 1

Acceleration Part 1: Learning Objective: average and instantaneous acceleration,  calculating distance travelled from a v vs t graph, formula to calculate distance travelled assuming constant acceleration. Contains Keynote (powerpoint) presentation. Continue reading Acceleration (motion under constant acceleration) – Part 1

# Motion in 1 dimension- Part 1

Learning Objective: Understand motion, velocity and speed

Vocabulary:
displacement
velocity
average velocity
speed
scalars and vectors

How is velocity measured?

Now calculate Big Daddy Don Garlitz’ average velocity by converting 0.25miles/5.40sec into miles per hour.

(0.25miles)/(5.40sec) x (3600sec/hr) = 166 mph
Why is this different than the 270 mph recorded top speed?
