An object is in motion if it changes position relative to a reference point. Motion is a relative quantity and is expressed in respect to the position of another object. Example: both a car and the Earth are moving (earth is revolving around the sun) but if we express the motion of the car in respect to the Earth, we say the car is moving relative to the Earth. At the same time the earth is moving relative to the sun.

How can you tell when an object is in motion?

Its position changes relative to a frame of reference.


What is it when an objects position changes relative to another object?

When an object's position changes relative to another object, it is called motion. This can refer to an object changing its location, orientation, or both in relation to another object.


When an object's position does change what is the change called?

When an object's position changes, it is referred to as motion. Motion is the change in position of an object over time relative to a reference point.


How do we use reference points to determine whether motion has occurred?

Reference points are used to determine motion by comparing the position of an object relative to those points over time. If the object changes its position relative to the reference points, then motion has occurred. By observing the changes in the object's position relative to fixed points, we can determine its motion, speed, and direction.


When is an object said to in motion if it changes in time?

An object is said to be in motion when it changes its position over time relative to a reference point. If an object is moving, it is undergoing a change in its position with respect to its surroundings.


Motion occurs when an object changes its location or its?

Motion occurs when an object changes its position relative to a reference point or frame of reference. This can involve changes in location, orientation, velocity, or acceleration of the object.


Describe How you determine whether an object is in motion?

An object is considered in motion if its position changes relative to a reference point over time. This change in position can be observed by tracking the object's movement or measuring its displacement. Furthermore, motion can be determined by calculating the object's velocity, which is the rate at which the object's position changes.
