Non-Uniform Motion - a body covers and equal distances in a set and given time intervals it is said to be in non uniform motion. In a graphical representation uniform motion can be represented by a straight line. For example a car moving at a steady speed on a straight road. Uniform Motion - a body said to be in uniform motion when it moves in a straight line at a constant speed. The orientation of the body in space does not change, but the trajectories of individual particles of the body are curved. In this motion all particles travel the same distance following a parallel straight line.Ĭurvilinear Motion – It is a path of motion in a curved line. Rectilinear Motion – It is a path of motion in a straight line. Basically, in linear motion an object travels the same distance at the same time and the object can move in a straight or a curved path from one point to another.ĭepending on the path of motion linear motion is further subdivided as: In linear motion, the particles will move from one point to another point either in a straight line or a curved path. While describing the Linear Motion we require only one coordinate axis along with time to describe the motion of a particle then it is said to be in linear motion or rectilinear motion. In general, a body will be said to be in motion if it changes its position with respect to a reference point and time. Motion is described in terms of the following terms: Distance, Displacement, Speed, and Time as discussed above. The motion can either be fast or slow, but motion always exists. Every physical process happening in the universe is composed of some sort of motion. The fundamental particle of a matter i.e., atom is also in constant motion.
We live in a universe that is in continuous motion. Linear motion meaning the change of position of an object with respect to time interval. For example, a gymnast swinging on a ring. Reciprocating Motion - this motion is a continuous up and down or back and forth motion. Linear Motion - this motion is a one dimensional motion that takes place in a straight line. Oscillatory Motion - in oscillatory motion an object repeats in the same motion continuously back and forth. Rotatory Motion - this is a kind of motion in which the object rotates around a fixed axis. With respect to the nature of movement, motion is mainly categorized into four different types: Even though this universe is in continuous motion, but, there are different types of motion which will make your understanding more detailed and clear. For example-a moving train, a rotating fan, a ball rolling around etc. It can be defined as a process of changing position.

Motion is the free movement of a body with respect to time. With respect to the nature of the movement, motion is classified into three types as follows: Let's understand more about classification. In this topic, we have discussed the linear motion definition. Depending on the path taken by the particle the motion can be classified as projectile motion, rectilinear motion, rotational motion, and many more. Some objects move in a curved path while some in a straight path and a few others in a zig-zag way. As we can notice that different objects move in different ways. There is a change in the position of the object involved in these activities.įish swimming in the water, dropping of stone from a certain height, the flow of air which is coming in and out of our lungs, the automobiles carrying passengers from one place of pick up to the destination is also an example of motion. Our daily activities including walking, running, etc. It requires both the magnitude and direction for complete representation. While displacement can be defined as the shortest distance between the initial and final position.
It can be represented by a magnitude only. The distance can be defined as the total path covered during the motion. So, with respect to the change in the position, we have two quantities that can be used to describe any change in the position and they are distance and displacement. Whenever we speak about motion or rest it is always explained with reference to some fixed point which is known as the origin. We all live on this earth that is continuously moving, so now, are you in the state of motion or at rest? Well, finding answers to this complex question can be slightly confusing but let us break down the concepts and simply learn about motion and its types. But let us try to re-evaluate the situation. Let us assume that you are reading a book sitting on your sofa, now, think whether you are in motion or at rest? Clearly, here you are at rest.
