What is linear motion give two examples?
Examples of linear motion are a parade of soldiers, a train moving along a straight line, and many more.
What is linear motion and non linear motion?
Linear motion does not require a net force but nonlinear motion requires a net force. • A net force acting parallel to the movement will cause a linear motion; a net force applied in a direction not parallel to the movement will cause nonlinear motion.Oct 7, 2011
What is linear motion and its types?
Linear motion can be defined as the movement of a body on a straight line without any deviation. Important examples of linear motion are: An athlete running on a straight track of a park, a bullet shot from a pistol always moves in a straight line, etc.
What is linear motion class 9?
Linear Motion In linear motion, the particles move from one point to another in either a straight line or a curved path. The linear motion depending on the path of motion is further divided as follows. Rectilinear Motion – The path of the motion is a straight line. Curvilinear Motion – The path of the motion is curved.

What is linear motion in biomechanics?
Linear motion is movement in a straight line. Our body produces forces that cause angular motion of our joints that are then combined to cause linear motion of our bodies. This is known as general motion.May 25, 2017

What is uniform motion?
According to Newton’s first law (also known as the principle of inertia), a body with no net force acting on it will either remain at rest... A body in motion may be said to have momentum equal to the product of its mass and its velocity.
What is wave motion?
In sound, for instance, a single sine wave produces a pure tone, and the distinctive timbre of different musical instruments playing the same note results from the admixture of sine waves of different frequencies.
What is an encyclopedia editor?
Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. ...
Is there a difference between uniform motion and rest motion?
In fact, in classical Newtonian mechanics, there is no important distinction between rest and uniform motion in a straight line; they may be regarded as the same state of motion seen by different observers, one moving at the same velocity as the particle, the other moving at constant velocity with respect to the particle. ...
Who created the laws of motion?
Newton’s laws of motion, three statements describing the relations between the forces acting on a body and the motion of the body, first formulated by English physicist and mathematician Isaac Newton, which are the foundation of classical mechanics.….
What is the expression of amounts denominated in one currency in terms of another currency?
The expression of amounts denominated in one currency in terms of another currency by using the rate at which two currencies are exchanged. For example, a firm with foreign operations might express sales made in German marks in terms of U.S. dollars. Also called foreign currency translation.
What is parent-subsidiary relationship?
When a parent-subsidiary relationship exists between two companies in different countries using different currencies, the act or practice of changing the financial statements of the subsidiary to conform to the accounting standards of the parent's country, as well as re-denominating the subsidiary's currency into the parent's currency. According to the Generally Accepted Accounting Principles in the United States, the translation of a foreign currency to U.S. dollars must be accurate as of the date on the financial statement. If there have been substantial changes to the exchange rate since that date, the consolidated financial statement must note this.
What is duty cycle?
Duty cycle is defined in how often the actuator will operate and how much time will elapse between movements. Duty cycle is based on the number of expected repetitions per unit of time in hours per day, minutes per hour, and/or strokes per minute. Cycle times determine the life of a linear motion control system.
How do ball bearings travel in a ball screw drive?
In a ball-screw drive, ball bearings travel along the grooves in a threaded shaft and the ball screw and recirculate through a ball nut. Because bearings share the load, ball-screw linear motion drives have relatively high thrust capacity.
How does a nut work when it is rotated?
The nut is normally fixed and prevented from rotating with the lead-screw. When the lead-screw is rotated, the nut is driven along the threads. The direction of motion of the nut will depend on the direction of rotation of the lead-screw.
What is linear drive?
Linear drives move the carriage to the desired positions. The most common drive technologies are ball-screw drives, lead-screw drives, and belt drives. Linear Motion control system configuration, including the number of axes of motion, is often the first factor that needs careful thought. The most common are two-axis (X-Y) configurations, ...
What is a lead screw?
A lead-screw has a continuous helical thread machined on its circumference running along the length, similar to the thread on a bolt. Threaded onto the lead-screw is a lead nut or ball nut with exact helical threads. The nut is normally fixed and prevented from rotating with the lead-screw.
Why are gears used in motors?
Gears are used to allow a motor to be geared down to provide torque necessary to rotate the screw under a heavier load the motor would be capable of controlling directly . Rotary motion of the motor is converted into linear displacement of the actuator.
What is accuracy and repeatability?
Accuracy and repeatability are one of the most considered overall for the system, in which may deliver the desired quality or precision required in the system or manufactured end product. If the application for example is for an automated pick-and-place machine, high repeatability and accuracy are most likely required.
Different Types of Motion
As mentioned earlier, there are four different types of motion – ( 1) linear motion, ( 2) rotational motion, ( 3) circular motion and ( 4) periodic motion. Let us look into a short introduction of each type of motion
Difference between Linear Motion and Rotational Motion
Linear motion is on a straight road, whereas rotational motion is along a rotational axis; let us look into some more detailed differences between both types of motion:
Summary
Reading this article, we came to know about an introduction to motion which says that when an object moves from one place to another place, it is said to be in motion. Then we understood different types of motion: ( 1) linear motion, ( 2) rotational motion, ( 3) circular motion and ( 4) periodic motion.
Frequently Asked Questions (FAQs)
Q.1. What is the rotational equivalent of linear motion? Ans: Rotational equivalent to linear motion is those quantities that are similar in both types of motion. For example, the rotational equivalent of force is torque; linear momentum is angular momentum, mass is a moment of inertia, etc.
