Acceleration: Change in velocity over time.
Motion is relative, constant motion, no change detected.
We are going to explain different concepts of motion, the teks and more. Rotational, Translation Oscillatory and Deformation

The last one is not traditionally thought of but while a spring moves on a linear path it is caused by deformation of the metal.
Rotational = planets orbits
Translation = projectile path or linear
Oscillatory (Vibratory) = periodic like a pendulum, vibrations as in the vibrations of a string or the oscillating movement of a photon which moves in a linear fashion while vibrating
Deformation = motion inside of an object like tension, buckling, twisting, compression, or expansion. - Translation: Motion along a path
examples: Position, Velocity, Net force
- Rotational: Rigid of a body about an axis
- Rotational: Orientation of the axis, Angular position,
- Deformation: Bending, stretching, twisting,
examples: Internal elastic forces, springs, tension and compression
Real time technology is a set of systems and applications that respond in a timely fashion to requests for information and are composed of two essential components: timeliness and capacity. http://www.youtube.com/watch?v=2OJjbztWitk

## Motion

(B) Motion 1D problems can be broken down or separated into one or more 1 Denominational problems. You set up a coordinate systems with positive and negative directions (obviously).

Scalar- has only a magnitude, area or temperature.

Vector- has magnitude and direction like displacement or velocity.

Analyzing the motion of objects, 4 basic parameters; time, displacement, velocity, and acceleration. Time is scalar while the other three are vectors.

It's rather hard to identify the difference between scalar and vectors in 1D.

Displacement- represents distance traveled, final position (x), starting position (y).

Say you start in one position and move North 5 meters from where you started, your displacement is 5 meters North. If you turn around and go back with a displacement of 5 meters South. You would have traveled a total of 10 meters. Your net displacement is 0 because you're back where you started.

(C) Accelerated motion: motion with a continually increasing velocity. motion in more than one dimension that undergoes constant acceleration is given by the vector equation:

x(t) = a t 2 + v 0 t + x 0
