Answer:
If an object keeps on changing its position with time, it is said to be moving or in motion. Motion can be of different types: Linear or straight in which the object travels in a straight line. Circular in which the object travels along a circular path.
Explanation:
Distance is the total path covered by the object in the given interval of time.
Displacement is the shortest path covered by the moving object in the given interval of time.
Distance=Speed×Time.
Unit of distance is generally measured in units of length like metres, kilometres etc.
Introduction to motion
An object is said to be in motion if it changes its position with respect to time. Eg: A car moving on a road.
An object is said to be at rest if the object does not change its position with time. Eg: A person standing on the ground.
