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.

Displacement is distance moved by a particle or body in a specific direction. It is a vector quantity, possessing both magnitude and direction. The distance traveled by the point depends on the path that it follows; it will be equal to the magnitude of the displacement only if the path is straight. In mechanics, it is frequently necessary to distinguish between the distance that a point moves--or through which a force acts--and the displacement of the point or the force.
Based on the data obtained, Figure 1 represents a force vs. time graph for the amount of force that was used to pull a wooden block across a table. As illustrated in Figure 1, the initial flat line in the graph represents the block at rest, this is where the forces acting on the object are the normal force, gravity, and the static frictional force. Force was then applied to the wooden block until it began to move, the point at which the block moves is the peak in Figure 1. This is the point at which there was enough force applied to the block to overcome the maximum static friction force. The graph then begins to decrease because once a force is applied to the object that is greater than the maximum frictional force, not as much force is needed to continue to pull
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.

Motion Capture cameras are retro-reflective cameras used to help capture body motions in order to study the movements in space, also known as kinematics. Motion capture cameras can capture at 1 million millisecond intervals, making frames as high as 1,000 per second. There are two types of motion capturing cameras, 2-D and 3-D. Two-dimensional motion capture occurs when only using one motion capture camera. 2-D only incorporates the X an Y coordinates. When using more than one camera the Z coordinate is incorporated, making it a three-dimensional motion capture. Motion capture can be fairly cost effective when using only one camera and a computer to digitize the film into sequences of different frames. Then one can compare the videos and frames with other videos to help discover and form ideas to improve and further the knowledge on motion in space.
Every 4 years, the Olympic games is a major event around the world. International athletes come together to represent their own country at a sport. A gold medal is given to the winner of each game. This math internal assessment aims to consider the trends of the wining men gold medalist’s pole vault height from 1932 to 2008, and predicting 1940 and 1944 record, when the Olympic games were not held due to the world war.
Points on a coordinate plane that are or are not connected with a line or smooth curve model, or represent, a relationship in a problem situation. In some problem situations, all the points on the coordinate plane will make sense. In other problem situations, not all the points will make sense. In addition, when you model a relationship on a coordinate plane, it is up to you to consider the situation and interpret the meaning of the data values shown.
Movement is an everyday household word that we use instead of saying motion. Motion is a change of an objects placement in relation to the direction it went and time. Motion was explained by a now famous scientist who goes by the name of Issac Newton. He came up with the 3 laws of motion. The law that is being focused in is Newton’s first law, often called “Newton’s first law of inertia”. Newton’s first law is commonly stated as “An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted on by an outside force.” Put simply, an object that is moving will keep moving in the same direction and the same speed unless another force acts upon it and an object that isn’t moving won’t start moving unless there is another force that acts upon it. Inertia is the term that scientist use to describe the way that objects resist change in its motion. Inertia is directly related to an objects mass. The greater the mass of an object, the more inertia it has In other words, the heavier an object, the more resistant it...
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.
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).
