Chapter 12
12.1 Rotational Motion
Rigid body extended object whose size and shape dont change as it moves
o Good approximation for wheels and axles
o 3 motions:
Translational: object moves as whole
Chapter 4
4.1 Acceleration
v
=> same direction as the change in velocity
t
Instantaneous acceleration is comprised of:
a =causes the object change speed
o
Parallel to direction of motion: speed up if
Chapter 14
14.1 Simple Harmonic Motion
Oscillatory Motion repetitive motion back and forth around an equilibrium position
Oscillators
o Take place about an equilibrium position
o Motion is periodic
Test 1: Chapters 1-3 and Error Analysis
Chapter 1: Motion in one dimension
Basic Types of Motion
Linear, Circular, Projectile, Rotational rotation is a change of the objects angular position
Translat
Analysis in Experimental Physical Science Mini-Version
Uncertainty/ Error range of values associated with a measurement
Ex. Guessing the no. of apples => this number has an error
Error => not mean m

10.1 The Basic Energy Model
Joule: units are kg m2 /s 2 (scalar not vector)
Potential energy: Thermal energy: sum of microscopic kinetic and potential
energies of all atoms and bon
Chapter 11
11.1 Basic Energy Model review
Mechanical energy conserved: isolated, frictionless system
Thermal energy is the cause + there is no non-conservative
forces
System Energy: total energy of

1.1 Motion Diagrams
4 Basic Types of Motion
Linear motion
Circular motion
Projectile motion
Rotational motion rotation is a change of the objects angular position

4.1 Acceleration
v
t
Ferris wheel: constant speed, not velocity, so she is accelerating
o Acceleration points toward the center of the circle due to the
changing direction, not changing sp
Chapter 8: Dynamics II: Motion in a Plane
8.1 Dynamics in Two Dimensions
Newtons 2nd makes no distinction btw linear and 2-dimensional motion in
a plane
Projectile Motion: for low mass projectile
Ef
Chapter 7: Newtons 3rd Law
7.1 Interacting Objects
Interaction: mutual influence of 2 objects on each other
Action/reaction pair: 2 objects interact by exerting an action/reaction pair of
forces on
9.1 Momentum and Impulse
Collision: short-duration interaction between 2 objects
Time of collision: depends on materials of objects (harder shorter the contact time)
Impulsive Force: large force ex
2.5 Free Fall
Free Fall: motion of an object moving under the influence of gravity only, and no other force
Only in a vacuum, no air resistance
Effect of air resistance is small for heavy objects =>

3.1 Vectors
Scalar Quantity: quantity that is described by a single number
Vector Quantity: quantity with both a magnitude and a direction
3.2 Properties of Vectors
Displacement vector: a s
