What is mechanical movement? How to Judge Mechanical Motion?

The motion of an object's position over time is mechanical motion.

Movement is relative, so choose the appropriate frame of reference.

In middle and high school, the curvilinear motion and rectilinear motion that you learn are both mechanical motions.

Personally, I understand that mechanical motion is referred to as motion, which is due to the change in the position of an object relative to the reference object, and then mechanical motion occurs. Whereas, mechanical energy is a type of energy, which is the energy produced by an object during mechanical motion, including kinetic energy and potential energy (gravitational potential energy and elastic potential energy).

This ** deviates from the translation, the English word for mechanical motion is mechanicalmotion

So in fact, mechanical not only has the meaning of mechanical, but also the meaning of force and mechanism, so the translation into Chinese is accurate: it is an object under the action of force to do a certain mechanism of motion

1.Mechanical motion: The change in the position of an object relative to other objects, that is, the change in the movement of the position of the object over time, is called mechanical motion.

Mechanical motion is simply called motion, and the process by which the position of one part of an object changes relative to another is also called mechanical motion. For example, if a loss-making car is driving on the road, its position changes relative to the fixed object on the ground, and it can be said that the car has undergone mechanical movement. When a wheel rotates around a fixed shaft, the parts of the wheel are moving mechanically relative to the shaft.

2.Decision: As long as the position of an object changes relative to another object, the object is in motion.

3.Form: Mechanical motion is the simplest and most prevalent form of movement that we see. The movement of a car or a ship, the movement of celestial bodies, is a mechanical motion. Common mechanical movements are translational and rotational.

In physics, the process by which the position of an object in relation to another object, or the position of some parts of an object relative to other parts, changes over time is called mechanical motion. Mechanical motion is the simplest and most basic form of motion in nature.

What are the forms of mechanical movement

There are various forms of mechanical movement, some move along a straight line, some move along a curve; There are those that move on the same plane, and there are those that do not; There are those who move fast, and there are those who move slowly; Among the various forms of motion, uniform linear motion is the simplest mechanical motion.

A method for judging mechanical motion

Mechanical motion is a universal phenomenon in the universe, all objects are in motion, and absolutely stationary objects do not exist. The basis for judging whether an object is moving mechanically is to see if there is a change in the position of this object relative to another object. If there is, we say that this object is doing mechanical motion with respect to another object.

Examples of mechanical movements

1. The motion of the earth in an elliptical orbit around the sun (considered to be a uniform circular motion).

2. The car is driving at a constant speed on the horizontal road surface.

3. Electrons move in a uniform circular motion around the nucleus.

In addition, the rotation of bicycle wheels, the rotation of electric motors, the lifting of elevators, the movement of trains, and the rotation of range hoods are all mechanical movements.
