Motion is an object's change in position relative to another object, or reference point. The object that appears to s tay in place is called a reference point. The direction of an object's motion can be described with a reference direction, such as North, South, East, West, up or down. Motion is the action or process of moving or being moved. The greater the force acting on an object, the more it will accelerate. Motion make s the world go 'round' motion makes the moon go round too. The motion of a moving object can be ex plained using either Newton's law. The same concepts and principles used to describe and explain the motion of an object can be used to describe and explain the parabolic motion of a projectile. Motion is described in terms of displacement, time, veloci in one dimension is a good starting point for the description ty, and acceleration. The case of motion regard to the forces or energies that ma of motion. The study of motion without y be involved is called kinematics. Some motion is predictabl e in'theory but unpredictable in random. Motion is the movement i practice, which makes it appear n any direction. You can move up sideways. , down, forwards. backwards. and Examples of motion: 0 When you pluck the string of a guitar, the strings vibrate moving quickly back and forth. When water flows off a cliff, it creates a waterfall. When you throw a football into the air, it curves up... and then down again. Motion can be described by using visual representation like diagrams, charts and motion raphs. In describing motion, you are comparing it with some frame of reference. We define a frame of reference or point of reference as something that is used to judge or understand something else To decide if you are moving, you can use your chair as a reference point. A reference point is lace or object used for comparison to determine if something is in motion. An object is in motion if changes position relative to a reference point. Objects that are fixed relative to Earth - such as a building, a tree, or a sign - make good reference points. What happens if your reference point is moving relative to Earth? Have you ever been in a car parked to another car? Suddenly, you think your car is moving backward. But it was the other car moving forward. You seemed to be moving backward because you had used the other car as a reference point in motion. You seemed to be moving backward because you had used the other car as a reference point. Using graphs Another way to describe the motion of the ball is through the use of motion graphs. 15 Point of intersection Position (m) Position (m) (20s, 5m) Diagonal line 5 O 10 15 20 10 Time (s) Time (s) Figure 3 Figure 4 Science 7 Learner's Manual The graph that you have just drawn in Figure 3 is called position-time graph. You can also use this graph to describe the position of the ball at any given time. For example, if you are asked to find the position of the ball at 10 seconds, all you need to do is to find the point along the diagonal line where the vertical line at the 10 second-mark intersects (Figure 4). Then, find where the horizontal line from that point of intersection will cross the Y axis, which is the position axis. This will give you the position of the ball at 10 seconds.II. What is It What is wave? A wave is a periodic disturbance that moves away from a source and carries energy with it. For example, earthquake waves show us that the amount of energy carried by a wave can do work on objects by exerting forces that move objects from their original positions. Types of Waves There are two types of waves: the transverse waves, and the longitudinal waves. These are mechanical waves that require a medium for propagation. Water waves and rope waves are examples of transverse waves. On the other hand, a light wave is an example of an electromagnetic wave, which does not require any medium for propagation. Recall what you did when you generate waves in a rope. When you disturb one end of the rope, how did the rope waves travel with respect to the direction of wave motion? Yes, rope waves travel in a direction perpendicular to the direction of wave motion. This kind of wave is what we call a transverse wave. Below is an illustration of a transverse wave.On the other hand, longitudinal waves are waves which travel in a direction parallel to the direction of wave motion or parallel to the direction of vibration. The figure below illustrates longitudinal waves. Direction of wave motion coils vibrate in -line compression rarefaction one wavelength Transverse Waves versus Longitudinal Waves One way to categorize waves is based on the direction of movement of the individual particles of the medium relative to the direction that the waves travel. A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. Electromagnetic versus Mechanical Waves Another way to categorize waves is based on their ability or inability to transmit energy through a vacuum (i.e., empty space). Categorizing waves on this basis leads to two notable categories: electromagnetic waves and mechanical waves. An electromagnetic wave is a wave that can transmit its energy through a vacuum (i.e., empty space). Electromagnetic waves are produced by the vibration of charged particles. Electromagnetic waves that are produced on the sun subsequently travel to Earth through the vacuum of outer space. All light waves are examples of electromagnetic waves.A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Electromagnetic Spectrum The electromagnetic spectrum describes all the kinds of light, including those the human eye cannot see. In fact, most of the light in the universe is invisible to our eyes. The light we can see, made up of the individual colors of the rainbow, represents only a very small portion of the electromagnetic spectrum. Other types of light include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays and gamma rays - all of which are imperceptible to human eyes. All light or electromagnetic radiation travels through space at 186,000 miles (300,000 kilometers) per second - the speed of light. That's about as far as a car will go over its lifetime, traveled by light in a single second! Electromagnetic Spectrum Wavelength (meters) Radio wave Microwave Infrared Visible Ultraviolet X-ray Gamma Ray 103 10-2 10 -5. 10-8 10 10 10 -13 Frequency (Hz) Decreasing wavelength Increasing frequency 104 10 8 10 12 10 15 1016 10 18 10 20 Characteristics of Waves Water waves are easily produced and observed. By touching one point on the surface you can see the peaks of the waves form circles and move outwards from the source of the disturbance. Some of the characteristics used to describe transverse wave motion are enumera. The amplitude is the maximum displacement from the rest position. It is the height of the crest or depth of a trough measured from the normal undisturbed position. . The wavelength, A, is the distance between two successive crests or two successive troughs. It is also equal to the distance between any two identical points on successive waves. For example, points A and B and points C and D. Parts of a Wave WAVE CREST - AMPLITUDE WAVE LENGHT SEA LEVEL WAVE HEIGHT WAVE TROUGH The frequency, f, is the number of crests or troughs that pass a point per second. This is equivalent to the number of complete waves generated per second. Frequency is measured in terms of hertz (Hz). The period, T, is the time taken to generate one complete wave. It is also the time taken for the crests, or any given point on the wave, to move a distance of one wavelength. T = 1/f The speed, v, of the wave is the distance moved by a wave in one second. Since the wave crest travels a distance of one wavelength in one period, the wave speed, V = MT or v = fA Sample Problem: The frequency of some approaching ocean waves is 2 Hz and the length between two wave crests is 3 m. What is the speed of the ocean waves moving towards the shore? Given: f = 2 Hz 1 = 3 m Formula: V = f A = 2 Hz x 3 m = 6 m/s
