Concept of Motion

The concept of motion has its roots in the inception of life on earth, without motion, the civilization of humanity was not possible. The concept of motion is explained with the concept of acceleration, velocity, and displacement in order to comprehend the meaning of motion. The equations of motion are further mentioned to draw the correlation between motion and daily activities. 

What is motion? 

Motion refers to transformation or change of position or orientation in respect to time. On the other hand, when an object does not move with respect to time, it is said to be at rest or at a stationary position. All states of an object, whether in motion or at rest, can be described with respect to  a frame of reference which is actually moving together with the object. The state of an object whether in motion or at stationary position, cannot change unless it meets with force. Motion is actually explained through the concept of mathematics, which includes velocity, acceleration, displacement, momentum, torque. Velocity can be referred to as speed in a given direction whereas speed only refers to the extent of fast movement. Velocity states the speed and direction of the object in terms of motion. On the other hand, displacement is the shortest distance traveled by an object from its initial position to the final position. The term acceleration refers to the rate of change of velocity with time, which means that acceleration is the rate at which the motion of an object speeds up or slows down. For instance, motion along a line or a curve is referred to as translation, however, motion that changes the orientation of an object is called rotation. 

Equations of motion 

The equations of motion are a mathematical formula that assists in assessing the position, velocity and acceleration of a body in reference to a specific timeframe.  The equations of motion can be best described with the equation of kinetics, which governs the motion of an object in one dimension, two dimensions and even in three dimensions. The understanding of motion through kinetics is simpler as it is associated with variables derived from the positions of object and time.  It holds special significance because it can be used in identifying the trajectory of a particle as well. The equations of motion, from the perspective of mathematics, involve velocity, acceleration and the position of the object. The basic equation of motion is depicted through the concept that force (F) applied on the body is equal to the mass of the body (m) multiplied by acceleration (a), hence F=ma. There are three equations of motion, which are also known as the laws of constant acceleration.  The equations are only applicable when acceleration is constant and motion is seen as a straight line. In the equations of motion, which are mentioned below, acceleration is considered as a, displacement as s, initial velocity as and time as t.

• v² =u² + 2as
• v=u+ at
• s=ut+ ½at²

These equations can be used in assessing motion in daily life activities such as walking, jogging, driving cars. 

What is the significance of motion? 

The concept of motion can be used or referenced in the explanation of several events or events through a scientific perspective. The motion of objects or bodies is generally obedient to the laws of motion. Motions of a body close to the speed of light must be introspective with the theory of relativity while the motion of very small bodies can be explained through quantum mechanics. Therefore, the concept of motion of an object is usually related to the avenues of physics, which have great scope for learning. Motion holds great significance because motion is seen as a sign of life and without movement or motion, no step towards advancement can be taken. The importance of motion lies in the fact that it is seen as the manifestation of life at the expense of energy. On the other hand, it is motion with the help of which the earth orbits around the sun. Therefore, it can be suggested that without motion life on the earth would be impossible. As a correspondence to motion, the moon also orbits around the earth and other satellites orbits around their respective planets. The concept of motion from the perspective of mathematics helps a great deal in assessing the speed of motion at which the earth orbits around the sun. 

Conclusion

The concept of motion is important as it explains everyday occurrences for humankind. Motion is relative in explaining the movement of earth around the sun, explaining the reason why stationary objects such as trees appear to be moving from a moving train. It is important in calculating distance traveled from initial position to the final position as well.
