Take a picture of a object that you can balance (note: when balanced there is no rotation). Balance the object. Do
this three times to the same object balanced three different ways or to different objects if needed.

Absolute and Relative Angles
Absolute angles are measured with respect to a fixed external landmark. The Tower of Pisa,
shown below, has an angle of 86 degrees from the horizontal or -4 degrees from the vertical. A
relative angle, is
Kinematics is the description of motion. Linear refers to motion that is either a straight line
(rectilinear) or that follows a curved path (curvilinear). Linear kinematic vectors are acceleration,
velocity and displa

a) True (47%)
Linear motion is achieved by applying a force - rotary motion is achieved by applying a torque. A
torque, often called moment of force or simply a moment, is a force that is applied at some distance
from the axis of rotation that tends to
A Vector of Length 1
As a vector of length 1.0 rotates from all X
to all Y, its X and Y components change.
Center of Mass
In some cases we can represent an object as a single point in space. When we do this, we identify
the point on the object that best represents the objects total mass - this point is the center of mass.
Previously we learned that a fo

In this model we examine the relationship between the force applied to an object and the objects
