# 6 Types of Motion

6 types of motion is basically shown in all things, such as movement in our daily life like bus, car, and man running on road. The animals moving on road can be easily seen. The plants movement is very slow and is hardly visible among all living and non-living object.
So when the position of an object with respect to space or surroundings in earth, changes with time, the object is said to be in motion if and only if the object changes its position.

6 Types of Motion is given below in serial order

1. Uniform motion & Non uniform motion
2. Translator motion (rectilinear motion & curvilinear motion)
3. Rotatory motion
4. Vibratory motion
5. Circular motion
6. Oscillatory motion

6 Types of Motion are discussed one by one as follows:-

Translation motion: The motion in which the object or things move through the same distance and same time so it is called translation motion.
For example:-
1. A Bus or a scooter moving along a road.
2. A football rolling on the ground.
3. A Man sliding down a slope.
4. Pulling out table in room.

Circular motion: The motion in which the object or things moves about a fixed axis did not change its location is called circular motion. In other is called Rotatory motion.
For example
1. A spinning metal ball or stone.
2. A table fan.
3. The earth rotating around his own axis.

Oscillatory motion: Something moves as a whole, to and fro motion or back and forth or along the same path did not any change in shape. That kind of motion of such objects is called the oscillatory motion.
For example
1. We start a sewing machine. We saw needle of a sewing machine moving up and down.
2. The piston of a scooter bike etc.
3. The compress cylinder of a juice machine at a fruit seller shop.

Vibratory motion: The motion of a body where the moving body change in shape or size s called vibratory motion.
For example
1. The musical instruments generate vibratory motion.
2. A body breathing, when our chest expands or contracts.
3. The motion of vibratory is nature in our body. So all points on the chest do not move out equally.

Periodic motion: An object is repetitive motion. An object repeats itself an equal interval of time is called the periodic motion.
For example
1. The piston of a bus engine running at a constant speed.
2.  The moving pendulum of a clock.
3.  A human body beating 72 times in a minute.

Uniform motion: When a object covers equal distances and equal intervals of time along with a straight line, the body is said to be uniform motion.
For example
1. When aeroplane flying in a particular direction at a constant speed is uniform in air,
2. A train running straight in a particular direction at a constant speed are uniform motion.

6 types of motion use different formula.

Uniform & non uniform motion equations of motion of 6 types of motion:

1. v = u + at
2. S = ut + $\frac{1}{2}$ at2
3. v2 = u2 + as

So this is all about 6 types of motion.

Here,
v is denoted as Final Velocity
u is denoted as Initial velocity
a is denoted as acceleration
s is denoted as  distance travelled by a body
t is denoted as time taken.

Motion control

Motion control is a sub-field of automation, in which the position and/or velocity of machines are controlled using some type of device such as a hydraulic pump, linear actuator, or an electric motor, generally a servo. Motion control is an important part of robotics and CNCmachine tools, however it is more complex than in the use of specialized machines, where the kinematics are usually simpler. The latter is often called General Motion Control (GMC). Motion control is widely used in the packaging, printing, textile, semiconductor production, and assembly industries.

## Overview

The basic architecture of a motion control system contains:

• A motion controller to generate set points (the desired output or motion profile) and close a position and/or velocity feedback loop.
• A drive or amplifier to transform the control signal from the motion controller into a higher power electrical current or voltage that is presented to the actuator. Newer "intelligent" drives can close the position and velocity loops internally, resulting in much more accurate control.
• An actuator such as a hydraulic pump, air cylinder, linear actuator, or electric motor for output motion.
• One or more feedback sensors such as optical encoders, resolvers or Hall effect devices to return the position and/or velocity of the actuator to the motion controller in order to close the position and/or velocity control loops.
• Mechanical components to transform the motion of the actuator into the desired motion, including: gears, shafting, ball screw, belts, linkages, and linear and rotational bearings.

The interface between the motion controller and drives it controls is very critical when coordinated motion is required, as it must provide tight synchronization. Historically the only open interface was an analog signal, until open interfaces were developed that satisfied the requirements of coordinated motion control, the first being SERCOS in 1991 which is now enhanced to SERCOS III. Later interfaces capable of motion control include Profinet IRT, Ethernet Powerlink, and EtherCAT.

Common control functions include:

• Velocity control.
• Position (point-to-point) control: There are several methods for computing a motion trajectory. These are often based on the velocity profiles of a move such as a triangular profile, trapezoidal profile, or an S-curve profile.
• Pressure or Force control.
• Trans-mutational vector mapping.
• Electronic gearing (or cam profiling): The position of a slave axis is mathematically linked to the position of a master axis. A good example of this would be in a system where two rotating drums turn at a given ratio to each other. A more advanced case of electronic gearing is electronic camming. With electronic camming, a slave axis follows a profile that is a function of the master position. This profile need not be salted, but it must be an animated function.

Question:

Answers:If this is to due with physics corey is right, but it could also be vibrational, rotational, and free movment, these corisponde to the states solid, liquid, and gas

Question:

Question:OK, so I have a Science project, and I have to make up 3 rides that show different types of motion- Uniform motion- same distances in same times (such as a ferris wheel) Variable motion- different distances in different possible times ( like a falling object, depends on the wind, gravity, height, etc , but I don't really have an example?) Periodic motion- A motion that repeats itself over and over again( Like a swing, or a pogo stick) SO.... yeah and I just am asking for you guys to give me examples of them in amusement park rides... THANKS!!! BTW Its due on Dec 13.... so don't have a lot of time... BTWA... I have to make it 3-D.... so maybe give suggestions on how? But that's optional... so THANKS!!
