The book’s position lying on the table is not changing with respect to the table itself. Or, to be more specific, the rest of the body and the state of motion is determined concerning its surroundings. The change in the body’s position depends on its surroundings. Whereas the body’s position does vary with time, we say the body is at ‘ motion’. When the body’s position does not vary with time, we say the body is at ‘rest’. Rest and Motion are relative terms explain with Examples This occurs because of their relative motion between your car and other vehicles as the observer’s position changes with time. You may have noticed the vehicles are moving slowly past you even though you know their actual velocities, those are very high. Hence, the motion of the vehicles is absoluteas the observer’s position is not changing with time.īut when you travel in a car, you watch other vehicles passing by from the car window. Here, you are the observer, and your position is not changing. Suppose you are standing at the side of the road and watching all other vehicles passing by. Explain what is Absolute and Relative Motion with Examples? Moving Vehicles: The body’s position does not vary with time. When there is no fixed point for observing the motion of the body, it is said to be relative motion. the frame of the observer Absolute Motion Vs Relative Motion Absolute Motion Relative Motion When the motion of the body is observed from a fixed point, it is said to be absolute motion. Let’s make it clear that while defining the ‘relative motion’, the three things we should consider: To understand the motion of the moving body, we need to observe it from specific frames – to say the body’s motion is relative to that frame. That means the motion is not determined with reference to the earth but with the other moving body on the earth. The relative motion is the estimation of the body’s motion concerning other moving or stationary objects. Therefore, their motion is relative to the observer’s frames. The motion of two moving bodies might look different for different observers based on which frames they observed. But the next question is ‘ relative to whom?‘, When two moving bodies interact with each other, we can say their motion is relative. What is the Relative Motion Theory? Motion is Relative mean? Hence, whenever two bodies interact, those different frames describe the motion between interacting bodies as a ‘relative motion’. Examples illustrating ‘What is Relative Motion?’Īll motions have various appearances or perspectives as we view them from different frames. The theory of relative motion will help us understand why these motions appear different for different observers. Have you noticed that you appear stationary to the other passengers? But if someone sees you from the outside of the train, your motion appears similar to the train velocity to them. Suppose you are travelling with other passengers in a train that is moving at 40 km/hr. Let’s take one of the examples that explain the meaning of relative motion between two bodies. “The motion of the body is moving with respect to another body which is either moving or at rest, known as relative motion between both interacting bodies.” Relative Motion Examples The relative motion is the motion between two interacting bodies defined as
