Introduction to linear motion graphs
The change of location of an object along a straight line and can be described using a single spatial dimension is called linear motion. It can be uniform or non-uniform, that is, constant velocity or variable velocity. The motion of particle can be described in terms of X with time T. A very good example for linear motion is a ball throwing down and up straightly. Plotting of graphs under linear motion is called Linear motion graphs. Here we study about two types of graphs as displacement-time graph and velocity-time graph. The linear motion of graphs drawn with acceleration, velocity and displacement.

Upon completion of this task, the students will have photographs of different types of lines, the same lines reproduced on graph paper, the slope of the line, and the equation of the line. They will have at least one page of graphing paper for each line so they can make copies for their entire group and bind them together to use as a resource later in the unit.
This past semester I read the book Slam by Walter Dean Myers. The setting is in a run down part of town in a big city that was un-ginven. The story line is that Slam the main character is going to a new school that is a white school where he once went to a predominately was black and so is he. He is a senior going into a new school because of his grades; he also came from a school where he was one of the best basketball players. His friend was the best player for his old school. He also has a girl that he likes and the start going out. His dad does not work well not all the time his grandma is dying. The main characters are Slam, Goldy.
This equation shifts from the parent function based on the equation f(x) = k+a(x-h) . In this equation, k shifts the parent function vertically, up or down, depending on the value of k. The h value shifts the parent function to the left or right. If h equals 1, it goes to the right 1 unit, if it is negative 1, it goes to the left 1 unit. If a is negative, the parent function is reflected on the x-axis. If x is negative, the parent function is reflected on the y-axis.
Sensory signals relating information about our physical movements, as well as information regarding external object motion, are required in order to preserve a stable and accurate view of the world, and estimate external motion. Space constancy is the visual system’s ability to maintain a view of the outside world that does not jump about and move with an eye movement (Deubel, Bridgeman, & Schneider, 1998; Stark & Bridgeman, 1983). A simple way of achieving this is to add the velocity estimates that are derived from afferent and efferent motion signals. The sum of these estimates would result in head-centred motion. For instance, the image on the retina of stationary objects in the world would gain a motion opposite and equal to any eye movement. As suggested above, reafferent retinal motion should provide a velocity estimate of similar magnitude to the efferent estimates of eye movement. If these two estimates are equal to one another, but have opposite sign, then their sum would correctly suggest null motion.
A prominent phenomenon in the field of visual science is the motion after-effect (MAE) which is believed to provide a way of bringing together current knowledge of neurophysiology with a measurable visual phenomenon. The MAE is described as a visual illusion produced by viewing any number of motion types (i.e. lateral or vertical linear, spiral, radial or rotation). By viewing a moving physical object for a period of time until the eyes is adapted to the motion. When the motion of the object is stopped, but viewing remains focussed on the object, the viewer may report a slower, reversed/negative movement of the now stationary object (Mather et al, 1998).
An oscilloscope is a laboratory instrument that commonly used to display and analyze the waveform of electronic signals. This device draws a graph of signal voltage as a function of time. Oscilloscope usually have two-dimensional graph which electrical potential differences represent by Y-axis (vertical) and time represent by X-axis (horizontal). With positive values going upward and negative values going downward (Ask.com, 2014). In any oscilloscope, the horizontal sweep is measured in seconds per division (s/div), milliseconds per division (ms/div), microseconds per division (s/div), or nanoseconds per division (ns/div). The vertical deflection is measured in volts per division (V/div), millivolts per division (mV/div), or microvolts per division (µV/div).
Kinematics unlike Newton’s three laws is the study of the motion of objects. The “Kinematic Equations” all have four variables.These equations can help us understand and predict an object’s motion. The four equations use the following variables; displacement of the object, the time the object was moving, the acceleration of the object, the initial velocity of the object and the final velocity of the object. While Newton’s three laws have co-operated to help create and improve the study of
Finally, length contraction is apparent whenever an object is in motion. For instance, an observer on the Earth would measure the length of the rocket to be shorter when it is moving at its high speed as compared to its length at rest.

In the first Unit of class we talked about motion in one dimension, but in this unit we talked about motion two dimensional. One example of a two dimensional motion is projectile motion. Projectile motion is when an object has an initial force that is applied to it to begin its motion. After the object starts its motion there is no longer a force that is being applied. At this point in time The only two forces that are acting on the object the first one and that largest one is gravity. The second force is normally neglected, when doing a projectile calculation. This small force is air resistance and causes the object
In chapter 18, we will apply work and energy method to solve planar motion problems involving force, velocity, and displacement. But first it will be necessary to develop a means of
The amplitude, or A in the equation is 1/2 |max-min| of the height of the graph.
In our text we began our study of physics with motion because motion is a dominant characteristic of the Universe (Kirkpatrick, 21). In class we learned that speed is the distance traveled divided by the time taken, s=d/t. The definition of velocity is very close to that of speed except that direction of an object is also taken into account.
Lines are paths or marks left by moving points and they can be outlines or edges of shapes and forms. Lines have qualities which can help communicate ideas and feelings such as straight or curved, thick or thin, dark or light, and continuous or broken. Implied lines suggest motion or organize an artwork and they are not actually seen, but they are present in the way edges of shapes are lined up.
