What is the difference between distance and displacement?
Answers
Explanation:
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position

Explanation:
Distance is defined as the actual path covered by an moving object in a given time interval.
• It is a scaler quantity.
• It is always positive.
Whereas displacement is defined as the shortest path covered by an object or body.
• It is a vector quantity.
• It can be positive, negative or zero.
Let's take an example to understand this:
An athlete makes a complete round of a circular track of radius 10m.
Here, distance = circumference of circle = 2πr
Therefore,
Distance = 2 × 22/7 × 10
Distance = 22/(7*5)
Distance = 22/35
Hence, the distance covered by him is 22/35 m.
Since, the athelete make a complete round of a circular track. So, his displacement is zero as the initial and final positions are same.
