Types of motion, GLB and uniformly accelerated motion
Motion is relative:
Benda said to move the reference point is considered stationary. For example, motorcycle moving at a speed of 30 m / s he is said to move the reference point such as a silent observer. Another example of the passengers on the bus was sitting in a chair while the bus moving at 50 m / s being silent observers on the edge of the road, in this case the passengers said the bus was silent on the edge of the road was said to be moving towards passengers with speed - 50 m / s.
Everyday problems associated with the relative motion:
At the gate of SMAN Ngantang motorcycle moving to the right with a speed of 10 m / s, and also from the direction kambal car moving with a speed of 40 m / s. Andi quietly waiting for a bus at the gate beautiful flower.

Based on the trajectory of motion is divided into;
1. Straight motion
2. Circular motion
3. Parabolic motion
4. Random motion
Based kecepatanya motion is divided into:
1. Motion with constant velocity at all times
2. Uniformly accelerated motion with speed at all times
3. Motion with a speed change irregularly
Based on the position of moving objects in the field of motion is divided into rectangular
1. The motion direction of the x axis, eg straight uniform motion horizontal direction (GLB), uniformly accelerated motion horizontal direction
2. The motion direction of the y axis, for example the free fall motion (GJB), upward vertical motion (GVA), downward vertical motion
3. Motion blend the x and y directions, for example Parabolic Motion, Circular Motion.
Consider the following animation:

Consider the following animation:
The second ball was a slowdown positive horizontal direction acceleration direction opposite to the direction of velocity
The third is the circular motion towards accelerating toward the center of the circle and the direction toward accelerating pace Perpendiculars
The fourth motion Changed Regular deperlambat (a = -) and Vo is not zero, but the final velocity = 0
STRAIGHT MOTION irregular.
Motion to track a straight line where the velocity of the object always stays any time and the value of zero acceleration.
The plus sign indicates the starting position, the distance to the next point shows the position change per time.
gravik left (st), middle graph (vt), while the right graph (at) where a = zero or has no acceleration.
In terms of the amount of displacement straight motion with great mileage and speed equal to that obtained kelajuannya formula:
Uniformly accelerated motion.
That motion to track a straight line, and the speed with regularly changing every time. Changes in velocity per unit of time is what is meant by acceleration. Acceleration can be positive or negative.
Graph left (st) form kwadratik function in the form of curves, graphs middle (vt) be a linear function indicates that the speed is always changing and the right graph (at) shows the value of the acceleration constant (not zero)
Compare and learn the differences animations and graphs of uniformly accelerated motion and GLB. So that the physical quantities are uniformly accelerated motion, and the new acceleration. Formulation:
